System freezes... what should I check first?
Twice my system has locked up in the past few days, and I'm not sure where I should start to look for problems.
I am running a hard-drive install of kanotix (debian), with kernel 2.6.6, and using Xfce. I believe both freezes occured using Firefox (although the first time may have occurred in Opera). The screen freezes but the mouse cursor still moves. Ctrl-Alt-Backspace doesn't reset X, and I have to do a hard-reboot.
Where should I begin looking for problems? I checked /var/log/messages and /var/log/XFree86.0.log, but I'm not even sure what to be looking for.
Thanks in advance
