To embed some additional functionality in the tlb refill handler, I
replaced the synthesized refill handlers in 2.6.16 linux with those
from 2.6.6 (for example tlb-r4k.S under arch/mips/mm-32). Everything
seem ok when I bring up one CPU, but causes unrecoverable exceptions
in the kernel when I bring up multiple CPUs. I explored if that could
be because of unflushed icaches on other CPUs. but that doesn't seem
to be the case.

Have anyone run into similar problem ?

thank you,
