Hello all
On my ubuntu hardy (8.04) with 2.6.24-22-generic (from ubuntu), I have a
reproducible problem with my lenovo thinkpad T61p 6460
I have an advanced minidock for the thinkpad. Normal docking and
undocking work great. However, if the dock loses power while the
thinkpad is docked, the computer freezes.
At that point, I can reconnect the power and wait a short while (in the
order of 5-10 seconds) to resume normal operation. If I don't reconnect
power (this I discovered when there was a local power outage), then the
computer seems to be locked for a long time (in the order of 10-20
minutes). However, it did finally start responding again, although I
cannot remember if any external event triggered it (but it was before
power had been restored).
You'll find below the debug messages from before the powerloss, and up
to the point where the computer started responding again. As you can
see, USB disconnects properly, and then there's a 773s (~12m) pause
until the section beginning with "NMI: IOCK error" begins.
Does anyone know what could cause this, and how it could be fixed? It
really seems like some part of the kernel is waiting for an event that
will never occur, because power has been lost.
Any ideas?
