Folks,
At OSDL we're seeing a wierd performance crash on 8.1cvs. What's wierd about
it is that it doesn't happen all the time -- about 1 out of 4 test runs.
What it looks like happens sometimes is that performance drops dramatically
at the first checkpoint, and never comes back. But there's oprofiles and
things to make a more insightful analysis:
3 test runs exhibit it:

Note that these are all different day's builds.
