Chris, we are trying to add DP HW configs to the CI and QA systems so bugs like this are found proactively. If you can tell us the HW config you used when this bug appeared, it would be very helpful.
let's follow this with the latest one. *** This bug has been marked as a duplicate of bug 97551 ***
