Public bug reported:
linux-image-2.6.37-7-generic 2.6.37-7.19
Intel wifi dies and is not usable again until the hard RF kill radio
switch has been toggled (the magic software-based firmware reload is
clearly not good enough in this case). Average uptime is then about 2.5
minutes (utterly useless) until the next death. There are various other
bug reports of Microcode errors over the last couple of years, but most
of them are Expired, or have different restart 0xNNNNNNNN codes. This
probably came from a recent natty upgrade upgrade as it has been
happening since yesterday: both in Millbank and the wireless I was
(trying) to use last night.
It appears to be a mode that the module gets in. Last night it was
eventually cured by a full reboot.
