Important question for everyone
Guys we have found out some important information regarding the timing issue.
Quote:

The P-state and C-state changes can affect the TSC and can result in TSC drift amongst the processor cores. The drift occurs only when the operating system uses TSC as the time keeping source. TSC drift can occur on K8 AMD multi-processor platforms and single-processor dual-core platforms as they do not provide frequency independent TSC. This drift does not occur on single-processor single-core platforms for obvious reasons.

Mercurysquad is now aware of this and is aiming to incorporate the Linux fix into the voodoo kernel.
I have a question for everyone suffering from this 'bug'. Is your motherboard based on the K8 chipset? I know mine is...
