tlbia instruction crashes for 405

[Shamile Khan]

Hi,

I am trying to get Linux to run on a Memec Virtex II Pro
board which has a Powerpc 405 core. I have 32 megs of
SDRAM. I get till the point below

loaded at:     00400000 004931D0
board data at: 00490128 00490140
relocated to:  00406618 00406630
zimage at:     00406C40 0048F6E4
avail ram:     00494000 02000000

Linux/PPC load: console=ttyS0,9600 mem=32M
Uncompressing Linux...done.
Now booting the kernel

After this the system hangs. Upon single stepping using an
abatron, I found the tlbia instruction to be the culprit.
This is the first instruction in initial_mmu in
arch/ppc/kernel/head_4xx.S. Its supposed to invalidate all
TLB enties. Any pointers as to why this instruction might
be crashing??

Thanks,
Shamile
