(Get the code!)
I had the same problem. It appear after update from 2.6.28-6 on 2.6.28-8 kernel and upper.
Firstly I've think it's video driver related but with 2.6.28-6 kernel, on the same driver it's work very stable.
I find in kernel.log this lines:
kernel: [ 21.198429] Marking TSC unstable due to cpufreq changes
kernel: [ 23.588616] agpgart-nvidia 0000:00:00.0: AGP 3.0 bridge
kernel: [ 23.588633] agpgart-nvidia 0000:00:00.0: putting AGP V3 device into 8x mode
kernel: [ 23.588689] nvidia 0000:02:00.0: putting AGP V3 device into 8x mode
kernel: [ 31.732343] Clocksource tsc unstable (delta = -63230109 ns)
After adding notsc clocksource=acpi_pm to grub kernel boot parameters. It stop freezing.
Hope it's help somehow.
