This is proposed as a Security Day 0 errata for 5.0.
Cleared rhel-5.0.0 and blocker and set rhel-5.1.0 flag.
Set pm_ack.

QE ack for RHEL5.

Comment 9 Mike Gahagan 2007-03-09 15:19:33 UTC
We haven't been able to reproduce the problem with the reproducer attached to
the rhel 4 version of this bug, but the patch is in the 8.1.1 kernel.
