CoreHI interrupts on Malta

CoreHI interrupts on Malta

[Jun Sun]

After shuffling some lines of printk(), etc, I suddenly get the following 
panics.  Anybody knows what they are?  They seems to be recursive, BTW.

If the interrupts really shouldn't happen, we probably should just disable IP5.

This interrupt comes from the Galileo system controller, when an error happens on
the bus.
Your are probably accesses an address out of range (beyond your physical memory
area).

This indicate a fatal error in the kernel, ignoring it wouldn't be wise.
