Just curious. Could the stray irq7's possibly indicate a hardware problem
which somehow only triggers stray irq7's when the hlt instruction is there,
but which can trigger a system hang in both cases? Might such a problem be
caused by the UDMA66 hardware (which was the last remaining variable and
which I removed from the system yesterday).
BTW, thanks for the explanation of the stray irq concept.
Regards,
Dave.
