Fedora 14 Lock-ups (system freeze)

[CS DBA]

Hi All;

I've been running Fedora 14 for several days now. I've had half a dozen 
instances of the system completely freezing. When this happens I have no 
mouse, no keyboard, nothing on the system works. I have to simply hold 
the power button and force a hard reset.

I'm at a loss as to how to debug this..  I've run a grep -i error 
against /var/log/messages and I get the below output, however I dont see 
anything that looks like it might be the issue..

I did try adding "clocksource=jiffies" to my kernel line in 
/boot/grub/grub.conf but the system locked up again after that so I 
reverted the change back to the original line without the 
"clocksource=jiffies" entry

Any thoughts on how to debug this?


Thanks in advance...
