Public bug reported:
Binary package hint: linux-restricted-modules
The Intel Pro/Wireless 3945abg controller in my new Thinkpad T61 sometimes
hangs, around once every twelve hours. I can identify no direct cause, although
I have only experienced this when on line power. Any attempt to remove the
ipw3945 module from the kernel after this happens also hangs, as does trying to
kill -9 NetworkManager. This may be a duplicate of bug #118110, but I never see
"microcode SW error detected. Restarting." in my dmesg. This is with
linux-image-2.6.22-11-generic and linux-restricted-modules-2.6.22-11-generic,
on Gutsy. Below is the end of /var/log/kern.log after a hang:
