Bug#628444: iwlagn - "MAC is in deep sleep", cannot restore wifi operation

My update (after a reboot caused by a crashed hibernation attempt at uptime ~8 

juhaj@rigel > uptime

(I think these are all defaults.)

rigel kernel: [1073316.734468] iwlwifi 0000:03:00.0: L1 Enabled; Disabling L0S

Linux rigel 3.2.0-1-amd64 #1 SMP Fri Feb 17 05:17:36 UTC 2012 x86_64 GNU/Linux

There have been TWO changes since I last had problems:

1. pcie_aspm=off
2. re-seating the iwlwifi mini-pci card in its socket

I am starting to believe I am in the clear here, but I am not yet convinced 
since the root cause is still unknown. In any case, thanks for all of you for 
helping hunt this down.

Dafydd: I think you might want to try pcie_asmp=off next
