Kernel parameters... X86_TSC

[Paul Lussier]

Hi all,

Is anyone here familiar enough with the 'Clocksource tsc unstable'
problem in recent 2.6 kernels to discuss the characteristics and
manifestations of this bug?

I'm looking to understand things like:

 - When the clocksource goes unstable, what happens from a userspace
   perspective?
 - Does time move at all?  If so, which way, forwards, backwards, either?
 - If the TSC clocksource is registered unstable, and the another
   clocksource is chosen, can it too become unstable?
   - If so, how will I know?  Will it log a similar error to the TSC error?
     Something like 'Clocksource [hpet,acpi_pm,jiffies] unstable' ?
   - What happens if the next clocksource goes unstable?

Please note, I'm NOT looking for a solution to the TSC problem, that's
readily available on the net.  I'm looking to understand the problem
thoroughly.
