RHEL5 fix for this issue
Comment 4 Michael Lampe 2008-12-15 12:04:18 EST
While the upstream patch applies to 5.2 kernels it doesn't work there because upstream has also changed the immediately following check-whine-and-fabricate logic. The check-whine-and-fabricate logic in 5.2 kernels will simply revert the fix-up and you end up as before.
Comment 5 Prarit Bhargava 2008-12-15 13:13:19 EST
Oops!  I attached (and submitted) the wrong patch.  Will try again with new patch.
