Default Bug#665881: module ath5k is blocking wlan-card

That's very good to hear. Can you reproduce this with 3.5.y from
experimental?

If so, please send a description of the symptoms to
linux-wireless@vger.kernel.org, cc-ing ath5k-devel@lists.ath5k.org,
Nick Kossifidis <mickflemm@gmail.com>, and either me or this bug log
so we can track it. Be sure to mention

- steps to reproduce, expected result, actual result, and how the
difference indicates a bug (should be simple enough)

- which kernel versions you have tested and what happened with
each

- full "dmesg" output from booting and trying to use wireless in the
affected state, as an attachment

- any other weird symptoms or observations

Hopefully the symptoms will ring a bell for someone, who can provide
instructions or a patch to track down the cause further.

Hope that helps,
Jonathan

Well, I installed now 3.5-trunk-amd64 from experimental. First tests are
showing good results. I still could not reproduce the behaviour with this
kernel. But it is too early, to make a final conclusion. So I will test it now
for a few days and will then send a report.

Yes, if any strange behaviours occure, I will send them to the list. My
current system is debian-testing, which I am running on several computers
(mostly daily updated). These are 2 x amd64-cpus (a notebook Acer Aspire 7520G
and a Desktop PC) and my Asus EEEPC 1005 HGO (i386).

Yeah, that might be great!

Thanky for the help.

Best regards

Drat. Am I correct in guessing that the prebuilt 3.3.6 package from
http://snapshot.debian.org/package/linux-2.6/ reproduces it, while
3.4.1 does not?

Huh, I did not test those versions. I just tested 3.2-xx (stock debian
testing) and now at your advice version 3.5. (experimental)

If 3.5 will work, I can test 3.3 and 3.4, too, if needed.

Ah, I think I see where I misunderstood. When you said "The described
behavior appears EVERY TIME", did you mean that it appears after a
while (how long?), and not necessarily the first time you try to use
wireless after rebooting out of Windows 7 into Linux?

No, I meant it this way: I started Windows 7, then rebooted and started again
choosing "Linux", then the bahviour appeared every time (hmm, maybe "each
time" might be the better English expression).

So I guessed, that Windows switched something in the wirelesscard or the bus.

Ok, that is how I understood it the first time.

My question still stands: when it happened every time, did it happen
right away?

If it did, and assuming you rebooted out of Windows 7 to try it,
there is no need to test 3.5.y any more. We already know it doesn't
reproduce the bug under the same circumstances as 3.2.y did.

Hoping that clarifies,
Jonathan

Yes, it happened at once. Right after I booted Win7 and then booted into Linux
again.

It happened also, when I booted Win 7, shut down the computer, powered off
(power supply and power cell), and then started Linux.

Did I describe it now better?

So you know the reasons. That is really good news! I read about, that 3.5
changed several things in bus strategies.

Thank you very much!

Ok, very good.

No. We know the above because of the information you provided!

* 3.2.y triggers the bug reproducibly
* 3.5.y does not trigger the bug reproducibly

I have my guesses about causes, but I am keeping them to myself until
we have the additional information I asked about, namely how 3.3.6 and
3.4.1 do.

Thanks for your patience, and sorry for the lack of clarity.

I would like to help. Can you tell me, where I find the packages of 3.3 and 3.4
images? I did not find them in the debian repositories.

No problem.
