I believe we had written this test to debug the other test with a lower overhead clocksource. Unfortunately, the tsc is x86 specific, isn't consistent across CPUs on certain systems, and can have it's frequency changed depending on by power states. For all those reasons, I agree with subrata, and this test can simply be removed from the LTP. -- Darren > > Regards-- > Subrata > > > > Sebastien. > > > > ------------------------------------------------------------------------- > > This SF.net email is sponsored by the 2008 JavaOne(SM) Conference > > Don't miss this year's exciting event.
