Public bug reported:

Binary package hint: linux-image-generic

The following problem started with kernel 2.6.26-20 and still persists
with 2.6.26-21 on (K)Ubuntu Hardy 8.04.1, both installed via apt from
the official "proposed" repository (currently linux-image-generic

Returning to my desktop in the morning, I'm not able to unlock it: While the system still runs, everything works - but the keyboard is dead. No input possible. Logging in remotely via SSH is still possible, so I was able to capture the dmesg ringbuffer (see attachment: crash.log).

What I tried to avoid a reboot:
* disconnected keyboard (PS2) and reconnected it
* disconnected keyboard (PS2) and connected another one (PS2,USB)
* switched completely to USB keyboard, on crash tried rmmod usbhid && rmmod hid && modprobe usbhid

None of these revived the keyboard, since it was the code built into the
kernel that crashed. Since according to the log Bluetooth was involved
(BlueProximity was running to be able to [un]lock desktop with my phone,
which only worked occasionally), I now closed BlueProximity and removed
the BT stick to see whether that helps. Will report results then.

As the summary says, these Oopses happen almost daily - but there have
been a few days they didn't occur. So I will leave BT off for at least a
week or until the next Oops, whatever happens first, and update this bug
with the results then.

PS: I tried to switch back to the latest "stable" version (
from hardy-security), but when I booted that the graphic srewed up: It
could no longer handle the nvidia card, though the suitable linux-
restricted-modules are installed. I would be happy to get rid of the
"proposed" repo stuff (it's only in there since the Wiki said it's
needed for dist-upgrade from gutsy), so advices for this are also
