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, g. -- Grant Likely, B.Sc. P.Eng.
