Bug#556585: iwlagn gone bananas after a couple of hours
Package: linux-image-2.6.30-2-686
Version: 2.6.30-8
This happened on a lenovo x300 using the squeeze distro, I suddendly lost the
connectivity for the wireless card. I tried to reload iwlagn to no avail.
Everything seems to be fine on reboot, though
here is the lspci output:
