I'm using Host AP driver with MPC8260-based board, but I have not
tested it with MPC8xx boards.

So, the card was initialized properly? Was there anything strange in the
kernel log or did it look okay (e.g., Host AP driver reported firmware
versions, etc.)?

Could you please run this through ksymoops or manually resolve function
names for NIP and the backtrace? Without System.map (and kernel module
load points) this report is not very useful.
