Adding to the same, there is also a clocksource thing which shows up my in my syslog

Code:
Feb  1 15:03:25 shirish-desktop kernel: [ 3058.752047] Clocksource tsc unstable (delta = 146398779 ns)
the kernel used is 2.6.27-9-generic.

Code:
$ uname -r
2.6.27-9-generic
Looking forward for comments/suggestions on the same
