Lustre discuss - Nov 2006 - Re: Lustre-discuss Digest, Vol 10, Issue 22

The cpu utilization bug was 10112, it was closed based on the belief
that a patch from bug 10265 would fix the issue. That patch went to
1.4.7 Lustre according to the last comment, and we have not seen that at
snl yet in order to test again.
