Thanks for writing.  Your hardware is sufficiently different from
Roland's that I really want this as a separate bug.  We can merge them
later if they turn out to have the same cause.

To save a round trip: when filing that new bug, please include the
portion of your kernel log describing this warning (or full "dmesg"
output from a normal boot, which would be even better) as an
attachment.

Hope that helps,
