I'm seeing the same error as reported by Sami Farin earlier today [1], but

from my logs I can see that the issue is intermittent (2/3 failures). The

logs indicate that the issue was introduced with 2.6.22 as TSC sync was

correct for all boots with 2.6.21-6.


My system is also Pentium D: Intel(R) Pentium(R) D CPU 3.20GHz


Cheers,

Frans Pop
