Card dropped dead during normal use after several days of
operation, 2.6.27.4 kernel with compat-wireless-2008-11-17.

Removing/reloading module didn't restore the card.

Toggling rfkill switch also didn't have any effect.

Had to power off the system to get the card to come back.

I have seen the same symptoms on my X61 and I have no idea when this happens. It seems to be uCode issue. However I have no clue how to reproduce it reliably. It just happens sometimes. And the nasty part is that only a full reboot will fix it.

Regards

Marcel
