Note: there's not actually a panic. Beaker just *thinks* there was a panic, because it saw the string "oops", which generally is accompanied by a panic, since we have panic-on-oops set by default. This just appears to be a host-specific timer issue, and an unfortunate string collision from the warning message.

This has only been seen on planck.rhts.eng.rdu.redhat.com .

Engineering testing has been unable to reproduce this issue after updating the BIOS.  I'm closing this issue as notabug.  If you experience this issue, please open a new bug and record specific reproducing steps.
