Most nights, some time in the hour of 3AM my xorg process will increase to 100% cpu and gpu load will also increase to 100%. The process also becomes unkillable. I cannot
sudo kill -9 it or get back control with
sudo service lightdm restart. I also cannot switch to to a tty screen with
ctrl + alt + f1. To reboot I have to log in with ssh, but this is not perfect because if I reboot while it is doing this my ZFS pool will fail to mount when it comes back up ( that is where my /home is ).
Does anyone have any ideas as to why I can't stop and restart xorg, or even better, know why this is happening?
NOTE: For anyone who comes looking for the same problem. I disabled catalyst AI and made it through the night. I've been up for 1 day 3 hours now. My record for this month is 2 days and 19 hours without a problem. My all time record is 6 days without a crash. I'll post here if it crashes again or I'm able to set a new record.
UPDATE: My computer crashed today at 4:32AM. I rebooted at 9:30 and went to a 1 hour lecture, when I came back it had crashed again. I have reverted to the open source drivers for now =(
