Cut from Bug Description. ** Description changed:
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 can't be 100% sure.
