slow hibernate after upgrade

07-31-2012, 09:08 PM

Hi,

After wheezy dist-upgrade desktop hibernate is twice as slow as before.

It is not drive related because it also happens when I move the swap
space to another drive.

The kernel was upgraded in this upgrade among many other things.

If I stop X before hibernating the speed is as before.

Anyone have suggestion on how to get around this?

I've also found that putting the by Debian/unstable laptop into sleep
with Fn+F1 takes much longer than before. But this is more several
dozens of seconds vs a few seconds in the past.

It now takes 40 secs. to hibernate about 400.000 pages, before it took
about 15 secs. But wakeup is still fast: 12 secs.

But why does this happen? And how to circumvent it?

When I pin linux-image-amd64 it does not happen so it is the wheezy
upgrade to linux-image-3.2.0-3-amd64 that does it, but is it a feature
or a bug?

I can't reproduce the problem, even with the same kernel. I think that
the only difference is that I have an Ethernet cable plugged in. I'll
have to do more tests, with and without the Ethernet cable...

Indeed the problem seems to occur only without the Ethernet cable.
And this is not due to the kernel, but to wicd:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=637267

It tries to put wlan0 down (probably in some wrong way), even though
is isn't up.
