It means that the cpu took the interrupt (at level 10, the system clock)
but the interrupt register showed no interrupt was pending.

I've no idea why this can happen as currently only one cpu is designated
to field device interrupts. Maybe it's useful to look at what code is
at the PCs mentioned above.
