This bug (or a related one) triggers on my laptop (Dell Latitude E6420)
since I switched from Kernel 3.0-debian to 3.1-debian (AMD64). I believe
that the bugs happens after waking up from the suspension-to-RAM.

Since I switched to 3.1 Kernel after waking up from suspension my laptop
freezes very often and I need to hard reboot it, this is really
annoying. This wasn't happening with 3.0 Kernel and I believe that
iwlagn is the cause.

I have an Intel Advanced-N 6205 (rev 34) wireless card.

The other day I was able to get the following kernel errors after waking
up from suspension with this 3.1 kernel[1]

This 3.1 Kernel is the Debian precompiled one (linux-image-3.1.0-1-amd64)

$ uname -r
3.1.0-1-amd64


[1] Find here the dmesg part that comes after the wakeup from suspension:
