Could you try again on my tree
ftp://e-mind.com/pub/linux/kernel-patches/arca-19-...diff.gz and feedback?
I changed schedule_timeout() to avoid inserting the timeout timer if the
function is been recalled by a proces in in TASK_RUNNING state. That make
tons of sense. schedule_timeout() will also log if it's been recalled with
a state != TASKrunning or != TASK interruptible.

I read that problems arise when the system is been idle for some time,
maybe this is the reason everything has worked fine so far here...

I _think_ to be the cause of the problem with my schedule_timeout(). I' ll
try to reproduce here. Thanks and excuse me. I am doing my best (and this
night I had a long sleep so I hope to be more smart then yesterday today
;-).
