Comment 2 Amit Shah 2010-10-21 07:46:04 UTC
Additional testing note: the effect of this patch will be visible with host-side qemu modifications which aren't yet in RHEL6.  When testing, ask me for a brew build.

Comment 4 Jarod Wilson 2010-10-28 20:09:00 UTC
in kernel-2.6.18-229.el5
You can download this test kernel (or newer) from http://people.redhat.com/jwilson/el5

Detailed testing feedback is always welcomed.
