First question is how your port fails on SMP: Does it no longer get interrupts
so that you believe the it's interrupt controller related?
I do not know the MIPS arch and how it compares to ARM (which that other
document covers). Does it have something comparable to the per-CPU interrupts
(SGI, PPI) of ARM?
