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.
