Public bug reported:
iwlagn (running on Intel(R) Wireless WiFi Link 4965AGN, REV=0x4) became
very unstable after upgrade from linux-image-2.6.38-11-generic-pae
2.6.38-11.47 to 2.6.38-11.48
Reverting to 2.6.38.10.25 solves the issue.
I am pretty sure regression came from 47->48, but since 2.6.38-11.47 is no more
available, I am can't be 100% sure.
Usually driver starts hanging for few seconds/minutes and later stops
working at all (NetworkManager looses it)
