Comment 8 Tetsu Yamamoto 2008-03-03 12:00:22 EST
Fujitsu has been testing this fix with RHEL5.1 kernel for a couple of months, 
and found no problem.  The test includes stress test and performance 
measurement as well as basic function tests to create/destroy PV/HVM domains, 
Linux and Windows guests.  In addition, the fix was committed in the upstream 
half an year ago, so I believe it has been tested for sufficient time.

If what Yamamoto-san wrote is correct, can anyone please commit this fix
for rhel5.2 and change the status into MODIFIED?
