SubjectRe: 2.6.0-test11, TSC cannot be used as a timesource.
ok, so we've shown it's not dependent on the number of cpu's you have. 
Not dependent on the amd/intel mobo and cpu you have. Not dependendent
on if you're using akpm's test10 patch on test11 or not. So this seems
to be proving to be a real bug.
