Anybody know if the fix for the incorrect kernel behaviour that leads to data corruption will be available for RHEL4/5 kernels?

I assume you are talking about the "GART pages must be uncacheable bug", which affects AMD processors.

The kernel bug is http://bugzilla.kernel.org/show_bug.cgi?id=7768, which has now been closed after a patch was submitted.

I searched for the commit id in the Redhat bugzilla, and found it for RHEL5: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=238709. That bug says the fix has been backported and is in RHEL5 kernel 2.6.18-18.el5. But I don't see anything about backporting to RHEL4.

I see. So forget RAM >= 4GB on Centos 4 on AMD AM2. Hmmph.
