Description Steve Grubb 2006-03-31 16:21:33 UTC
Description of problem:
There have been some locking problems recently identified in the audit
subsystem. Patches have been sent upstream. The patches should be applied to the
RHEL4 kernel, too.

Comment 1 Bob Johnson 2006-04-11 15:53:47 UTC
This issue is on Red Hat Engineering's list of planned work items 
for the upcoming Red Hat Enterprise Linux 4.4 release.  Engineering 
resources have been assigned and barring unforeseen circumstances, Red 
Hat intends to include this item in the 4.4 release.
