I opened bug 494927 with Red Hat after seeing this kernel error on two
different hosts, just a few days after updating or installing CentOS 5.3:
Has anyone else seen this yet? The patch that RH included in
kernel-2.6.9-78.0.17.EL.src.rpm to fix the problem appears to have been
in their 2.6.18 rpm since revision 15, so something else is apparently
causing the same problem.
I'm running bonnie++ in a loop on a VM running the affected kernel
hoping to duplicate the problem.
