Comment 1 Tuomo Soini 2009-03-10 06:47:46 UTC

This same problem is with rhel 5.3 kernel 2.6.18-128.el5.

Comment 2 Tuomo Soini 2009-05-15 12:20:10 UTC

Original patch seem to work stable with kernel 2.6.18-128.1.10.el5

Comment 3 Jes Sorensen 2012-05-08 14:14:05 UTC

Sorry, this bug slipped through the cracks.

Is this still an issue that needs to be addressed in RHEL5, or can we
close it? The fix in question should be in RHEL6.

Thanks,
Jes

Closing - if you see again, please reopen.
