Mph, that's no good.
What kernel do you use now? Any changes? Can you use "alt+sysrq; w"
while in that state to get backtraces for blocked tasks, in case it
helps find a deadlock? (You may need to use "echo 1>/proc/sys/kernel/sysrq"
before that will work; see Documentation/sysrq.txt for details.)
I have upgraded most machines to current stable and I have stopped
seeing thi.
Hope that helps,
Jonathan
