Hmm.. I got something like this on a single cpu pentium 3 with a nvidia
PCI gforce 2 MX (nvidia driver) and fc2 - but *not* often...

Kernel 2.6.9_1.6_FC2

It just *frose* yesterday (X) - and a quick ssh showed that ssh was
running at about 100% CPU... Keyboard led's etc. appeared to work, as
did ssh. Killing X didn't work - however it did die from a kill -9. But
the picture did stay on-screen untill reboot, when the BIOS came up just
fine.
