Public bug reported:
Binary package hint: compizconfig-settings-manager
OS:
Ubuntu 10.04.1 64 bit
HARDWARE:
AMD Athlon X2 5000
3 Gb RAM
NVIDIA 8600GT propretary drivers enabled and full functionally
Motherboard: M2N-E
NOTES BIOS:
Cool 'N Quiet function enabled
Last firmware updated to Deceber 2010
PROBLEM
Sometimes, when Ubuntu is stressed by heavy load, it crashes (freeze). No text
console or GDM restart could be executed..only Hardreset...
I've noted that this bug affects ubuntu only when Cool 'N Quiet function BIOS
was enabled (CPU frequency modulation). In last line of Kernel log was present:
kernel: [ 113.500027] Clocksource tsc unstable (delta = -69064579 ns)
I've noted that this problem perhaps affects even Microsoft Windows when
Cool 'N Quiet was installed because also in that case a strange "blue
death screen" appears in similar conditions.
I believe this is a BIOS or Hardware problem. Any ideas about it?
Most probably it's an "external" OS bug, but I would to report this
"bug" to contribute Ubuntu community.
