Clocksource tsc unstable (delta = 51799116882 ns)

Hi,

Since yesterday, some processes are really slow on my Lenny/Sid.
KDE clock is 10 hours late, bash is really really slow, keyboard 
repetition seems broken or really long to start, etc.

I found this in /var/log/messages:
[1510354.692239] Clocksource tsc unstable (delta = 51799116882 ns)

Can I do something to fix this without a reboot ?
