Sadly, my dpkg.log only goes back to 3.0, which was installed last July
(!).
I could try installing e.g. 2.6.32 from snapshot.debian.org if other
things don't help. But that would be a lot of patches to bisect,
especially when reproduction iterations are so long...

Linux nia 3.2.0-2-amd64 #1 SMP Sun Mar 4 22:48:17 UTC 2012 x86_64 GNU/Linux
The system is Debian unstable.
I don't use hibernation. I do suspend regularly, but I haven't noticed any
correlation with suspend/resume.

I'm currently waiting to see if wd_disable=1 help at all. This might
take a few days, though, since I don't have any way to reproduce it.

I haven't noticed any pattern. The first thing that happens is that
the NetworkManager applet seems to be trying to reconnect to the
wireless.
The log seems pretty quiet beforehand.
