Public bug reported:
Upon upgrade to Ubuntu 10.10 (and after that, re-installing clean with 10.10,
the issue appeared to be gone but has come back), I see a lot of this in
/var/log/messages*:

This is repeated quite often and eventually the machine hangs dead (even
sysrq keys don't work).
It seems that the issue is antagonised by my external 2TB drive which
was connected on eSata. Powering off and reconnecting the drive via USB
(at least 2x slower when working with files!), the problem goes away.
The messages can be triggered by copying to the device. The drive is not
a problem though -- palimpsest reports the drive is OK and, as I've
reported above, connecting on USB makes the problem go away (and the
problem wasn't present in prior revisions of the kernel).
This wasn't a problem before 10.10; 9.10 worked fine with this through
several iterations of the kernel. It seems that a kernel update around
10.10 has caused the problem to rear its head. Please advise if I can
furnish any more info. I'm considering trying a vanilla, latest kernel
from kernel.org compiled for my system to see if the problem is there
too -- please advise if doing so would be helpful as I'll do so sooner
rather than later.
