This may indicate a problem with interrupts; IIRC the kernel enables
interrupts immediately after printing that message. (If you UTSL look
for where the kernel calls spl0()).

Your parallel port and SB are sharing the same interrupt; this is Bad.
Try disabling the parallel port (or at least its interrupt) and see if
the problem Goes Away.
