The V2pro is already supported in the 2.6 kernel.  Are you using that
code; or starting from scratch?  V2Pro (ML300) and V4FX (ML403) are
both supported in the latest 2.6 kernel.

I had similar problems when I was porting to the V4FX.  Do you have a
JTAG debugger (Like a BDI-2000)?  I think your best bet is to get in
there with a debugger to find out where it goes off into Lala land.

Cheers,
