This is the full log? I see other /var/log/messages excerpts from the
gentoo bugzilla. Just wondering if there were any other warnings in
the log that precede the failure?
Can you attach the kernel configuration file to that bugzilla as well.
It sounds like you can reproduce it reliably. Is this a recent

might be able to bisect.
