All,

I'm trying to port the mips-kernel to a RM9000x2 based custom board.
The kernel file (mips 32) is loaded using VxWorks boot loader.
I got the to the point where the kernel starts loading, but exits with a 
'TLB load exception'.
After putting in a number of printks, it seems that it fails on 
'flush_icache_range' in arch/mips/mm/pg-r4k.c -> build_clear_page.
Since I'm a newbie to this, any pointers to how to tackle this problem 
would be appreciated.
