spurious interrupt occuring for no apparent reason


I'm running on and edb7111-2 rev b board.  Every once in awhile (once in
a blue moon), I get a spurious interrupt occuring.

TRACE: <5>[202]hal_arch_default_isr() Interrupt: 8
ASSERT FAIL: <5>[204]hal_arch_default_isr() Spurious Interrupt!!!

My program does not enabled EINT3 (int 8) in any way shape or form.  The
edb7111-2 ethernet driver for the CS-8900 does enable this interrupt
though.  But all it appears to do is IGNORE it.  By this I mean simply
ack it and then re-enable it.  So, this EINT3 problem should
theoretically never occur, should it?
