Comment 1 Yao Qi 2006-09-22 02:56:45 UTC 
Update kernel on rawhile.
These two cases do not hang box any more, but still failed.

Close this bug, and open new bugs against these test cases failures.
Comment 2 Yao Qi 2006-09-22 03:37:50 UTC 
Oops!  
testBlockingFibonacciFork hang the box again, and reopen this bug!
Comment 3 Yao Qi 2006-10-11 10:22:59 UTC 
Update kernel to 2.6.18-1.2747.fc6, and all these two cases do not hang ppc64 box.
