PDC20269 on PPC hangs

[Rahman, Masoodur]

hi ,
   I am trying to make the Ramix PMC243 module on the linux-2.4.20-pre2 from
the montavista site(IBM 750FX + MV64360) . The kernel seems to hang on the
partition check . The IRQ for the PMC is not shared with any other device.

Attached is the log for the 2 PMC sites during the bootup sequence...

and proceeds to the linux prompt.

Was there any patch available for the same ?? Was it fixed in the
linux-2.4.20 from kernel.org ?? I can migrate my patch to the linux-2.4.20
from kernel.org if that fixes my problem.....

Thanks a lot
