Default Bug#628444: Info received (iwlagn - "MAC is in deep sleep", cannot restore wifi operation)

Replying to myself, really, but two new observations:

> There were no problems in the 2.6-series. The bug occurs at least in the
> Debian kernel versions 3.2.0-1-amd64, 3.0.0-2-amd64, and 3.0.0-1-amd64.

As much as I thought and hoped this was true, it is not. I just had the
problem with 2.6.39, so...

> Do not have it now, if really necessary, will get it next time it occurs
> (which may be a while: I am back to 2.6.39 because I need to get work done).

now I have the dmesg, too. See attachment.

Now that I get this bug on a kernel version I never had it before, I am also
inclined to change my mind: perhaps this is not a regression in the kernel,
but in the iwlwifi firmware? I just updated my iwlwifi-firmwre to 0.35, and if
I still see this, I will go back to ~0.30 to see if that fixes the issue.

Now I wonder: could this be related to linux kernel bug #14141 [1] or other
similar problems that plagued iwlagn (predecessor to iwlwifi) in kernel
versions up to around 2.6.38 or so? It seems both bugs appear in similar
situations: after a little uptime (last case was less than 12 hours!) and
under heavy network traffic.

Cheers,
Juha

Down to 0.33, no help if running kernel 3.2. Now testing 0.33 & 2.6.39...

Default Bug#628444: Info received (iwlagn - "MAC is in deep sleep", cannot restore wifi operation)

On Wed, 22 Feb 2012, Juha Jäykkä wrote:


Replying to myself, really, but two new observations:


There were no problems in the 2.6-series. The bug occurs at least in the
Debian kernel versions 3.2.0-1-amd64, 3.0.0-2-amd64, and 3.0.0-1-amd64.


As much as I thought and hoped this was true, it is not. I just had the
problem with 2.6.39, so...

[snip]

As my original report noted, I have had the problem in everything from
2.6.36 to 2.6.39 (I also think 2.6.32 but am not certain and didn't have
the time to check). I don't recall what I said about firmware, but have
tried at least 5 different versions. I have almost completely stopped
using hibernate (suspend only) on my system and have not seen the problem
in a long time and for my system at least, hibernate seems to be related
to the number of incidents of the deep sleep bug.


While the firmware may play a role in the problem, at its core, there
are issues that must be occurring outside the firmware or even the iwlagn
driver, namely a kernel bug or bug in a supporting driver - there is
simply no way around this. When a machine has been through a hibernation
cycle and completely powered off with the driver unloaded before shutdown,
it simply cannot come back up with the "deep sleep" problem still in place
unless there is a bug in the kernel or some other driver involved. At
some point, outside software MUST be providing bogus information to the
driver. I say this because after the deep sleep bug occcurs and the
hardware has been power cycled (through hibernate), the device driver and
firmware have been reloaded and right from the start they show the "deep
sleep" state again. Everything related to the device has been completely
reinitialized so they cannot have any "knowledge" of past history or
status, so some piece of outside software is holding on to outdated
information and not updating. I demonstrated this repeatedly when I first
started fighting with the problem.


I also have other stability issues with the driver, the most irritating
of them is randomly "pausing" for periods of a few seconds up to several
minutes where no data gets through, as well as assorted other symptoms
consistent with race conditions between the driver and the kernel or
other drivers. Again, reloading the driver and/or firmware does not fix
these problems, or only does so sporadically.


Based on this behavior and the fact that Juha appears to have similar
hardware (though not the same model), and my previously noting that
many of the people complaining on the internet seemed to be using Lenovo
hardware, my recommendation to anyone who has time to investigate would be
to look at the Linux driver(s) for the flavor of PCI interface bus these
cards plug-in to and the particular chip sets used to implement this
bus on the known Lenovo machines having the problem (x201i, x200, ...).
My guess is they are using the same hardware and therefore, the same
interface driver. I don't know where else the bogus device status
information might come from or be stored, but I haven't been keeping up
with the Linux kernel for quite a while.


Note: my contact at Intel has not responded to my request for status, so I
don't know what if anything is happening at their end.

I never thought it was a firmware issue before, so I never paid any attention
to the firmware versions before. But now that I am back to 0.33, it looks
stable – although it is just 24 hours since last problem, that is nevertheless
towards the longer intervals. Usually it is just a couple of hours unless the
workarounds are on, which they are not at the moment (because I wanted to test
this).

I never had any issues with hibernate or suspend and certainly neither was
ever needed to trigger the bug. For example yesterday, I hit the bug after
about 3 hours without ever putting the laptop off my lap meanwhile.

This is past my knowledge and understanding, but it seems reasonable enough.
Is there anything I can do? If the pci bus is the reason, it might explain the
random freezes I have been experiencing (see #575965 for details), too.

Ok, so I just hit the problem while writing this up: 0.33 & 2.6.39 does not
help. Attached is what happened when I turned the HW kill switch after the MAC
went to unrecoverable deep sleep. Perhaps that backtrace can help figure this
out.

What is VERY strange here is the fact that I did not have this problem before
going from 2.6.39 to 3.0.0, but not I have it even with 2.6.39! How can that
be?!? What else is involved with talking to the wifi card except the kernel
and the firmware? Do I need to downgrade iwconfig et al, too?

This is *very* annoying. I now need to boot more than once a day compared to
once every few months before!

For a complete power-cycle, you may need to remove both the power cord
and the battery. I don't think the Intel wireless cards have any
support for wake-on-WAN, but in general devices may still be partly
powered as long as any power source is connected to the system.

The log messages you sent are indicative of a total failure of
communication with the card. My suspicion would be that the hardware
has developed a fault, but it could be as simple as the card being
slightly loose in its slot.

Having said that, are you setting the pcie_aspm kernel parameter?

The same code is used for PCI and PCIe devices and bridges of all kinds.
The only slot drivers are there to support hotplug.

True enough, and I don't remember if I pulled the battery back when I was
going after this problem (it has been almost a year since I did all my
tests). There is also a switch on the side that kills all RF devices
(WLAN and Bluetooth) but I can't verify that it completely kills power to
the devices.

Hardware failure might make sense except that it has always behaved this
way, others have similar symptoms, and most importantly, regardless of
what behaviors are occurring (there are a number of problems this card
exhibits), while hibernate won't clear the "deep sleep" problem, rebooting
the system (without power cycling) clears the problems EVERY time.
Whatever the trigger (intermittent hardware fault or driver bug), it
appears the kernel is getting into a state from which it is incapable of
recovering.



Having said that, are you setting the pcie_aspm kernel parameter?


No, wasn't even aware of its existance. System shows it is currently at
"default" unfortunately, the debug kernel I am currently running has the
pcie_aspm regression which prevents it from being changed without
rebooting which is rather time consuming with my setup. There doesn't
seem to be an obvious way to tell what the "default" is.


I should note that I have not seen the "deep sleep" problem in many
months, though it is hard to say when or if it has stopped since it often
took weeks to show up and my usage patterns have changed considerably. In
particular I noticed that hibernate for my system seemed to be a
significant contributor to triggering the bug since the problem often
showed up in the first few minutes after bringing the computer out of
hibernation. This is not a requirement to trigger the problem, just
significantly increased the odds.


NOTE: I stopped using hibernate in large part because of the "deep sleep"
bug. Unfortunately, the other problems of this card continue to plague me
(chronic random communication failures being the big one).

AFAIK the switch on Thinkpads does not kill power to the wireless card.

I'm not recommending that you set it. I was concerned that forcing ASPM
on could possibly trigger this problem.

After looking up the setting, I had assumed that was your concern.
However, it seems to me that if it is currently on, then forcing it to
"off" might possibly help with the issues with this card. Power
management has caused a lot of issues on Linux over the years.
Unfortunately, "default" doesn't tell me which state it is actually in.

Will give it a try next time I reboot.

FWIW.

Sure, I did: detach the cord and battery, wait ten minutes, then plug them
back in. No use.

Total? How come? It does detect the card correct, except the revision, which
is 0xFFFFFFFF instead of 0x24 as it should. My guess is the final error comes
from the incorrect revision number – of course it probably fails already
somewhere earlier and simply getting the revision right (which could be hard-
coded in the driver) probably would not help.

> Having said that, are you setting the pcie_aspm kernel parameter?

Like Shannon, I have not touched it at all, so it is probably off (whatever
the default is).

One thing I tries, is turn all PCI* related power-save features off from the
BIOS, but that did not help.

My most important question is: how do I get back to the working state? Going
back in driver and kernel versions does not seem to help!

I admit that the above sounds like a HW failure, but like Shannon, I do not
believe it because a full *kernel* reboot *always* fixes the issue. Why would
a faulty hardware get fixed when the kernel gets rebooted, but NOT when the
computer power gets completely turned off and all the hardware reinitialised
during a hibernate cycle. I even tried the following sequence: hibernate,
unplug power cord and battery, wait a few minutes, plug back in, reboot *a*
*different* *kernel*, see that the wifi works with this kernel, shut down,
reboot with the original kernel, unsuspending from hibernate. At this point,
the wifi does not work. I think this is quite a strong indication that this is
NOT a HW issue.

But what makes me most confused is that rolling back to versions of wireless-
tools, firmware-iwlwifi, and kernel does not give me back a working system,
which does suggest a hw failure.

Shannon: FWIF, I have now rebooted with pci_aspm=off and we'll see what
happens.

Ben: I also replugged the wifi card.

Also, I am back to 3.2.6 and newest firmware (I forgot to roll back the newest
wireless tools).

It wasn't required to trigger the problem on my system either, but it

On my system I could go for weeks without incident, and then have it
happen three times in a couple hours. It also appeared to be more
prevalent with some versions of the kernel than others (though this may be
an illusion due to the irratic nature of the problem). How long did you
run it on 2.6.39 previously? Perhaps it would have happened with 2.6.39
previously had you used it for a longer period?
