*** Bug 189031 has been marked as a duplicate of this bug. ***
committed in stream U4 build 34.19. A test kernel with this patch is available from http://people.redhat.com/~jbaron/rhel4/ However, there is a *serious* slab corruption issue with this kernel, and thus it should not be released to customers under any circumstances. I'll update this bug when the kernel is stable again.
We've identified the corruption as specfic to x86-64 smp kernel builds 34.16 and 34.17. All other builds are safe for consumption.
