My shiny new server panic'd this evening.

Panic: kernel diagnostic assert "si->si_refs > 0" failed: file "....
	arch/powerpc/powerpc/softintr.c" line 116


I looked in the CVS repository, and si_refs looks pretty local to this file,
and this file does not appear to have been changed appreciably since its
initial creation.

Anyone seen this bug, or have any ideas about it?  It is apparently
complaining that the soft interrupt queue(s) are corrupt.
