Spurious interrupts have been discussed a few times before. I suggest 
searching the archives.

Basically they occur when an interrupt happens, but no handler was set up to 
handle it.

Two typical causes:
1) Fiddling with the VIC while interrupts are enabled. Disable interrupts at 
the ARM code level (ie in the CPSR) while fiddling with the VIC.
2) Erroneous VIC set up.
