Description of problem:
Kernel 2.6.14-1.1777_FC5 causes the System to hang regulary and within ours of
booting up the machine.
Version-Release number of selected component (if applicable):
I attached the information I got using netdump.
Created attachment 122586 [details]
netdump log after system hang
May I see /proc/interrupts for that box (before the lockup, but with
most devices loaded, e.g. the 3D and USB in use.)?
I ran a little script dumping the time and the contents of /proc/interrupts into
a file every 30 seconds. Here is the last entry (the crash occured at 20:20:37):

By the way I'm running kernel 2.6.14-1.1752_FC5 for now which does not exhibit
the hanging bahviour (I booted into 1777 for the above dump of course).
I tried 2.6.14-1.1806_FC5 today and locks up just like 1777 after a short while.
It seems the problems where related to a faulty fan on the graphics card.
Replacing the card with a new model and running it for a few days fixed this for me.
