If I leave my laptop idle for a long period of time, it tends to lock up
with the CPU fan spinning fast (presumambly because some part of the
kernel tries to acquire a lock and spins constantly for it).
Unfortunately, this happens when X11 is running and I can't break into
DDB to snoop around.
I did notice that if I leave a terminal running:
$ while true ; do \
echo -n "$(date '+%Y-%m-%d %H:%M') " ; \
tail -1 /var/log/messages ; \
sleep 10 ; \
this works as a 'workaround' for the hardlock.
The sources of /usr/src have been updated up to:
Any ideas how I could try to debug this?
