I am running io-pkt-v6-hc on a PPC460.  A memory fault (core dump) was detected by my verification engineer on our board
.  I have run gdb on the corefile (no symbols).  Can someone tell me if the trace information:

a. iis ndicative of a problem that happened while initializing io-pkt or the shim layer.
b. is a known problem with a knonw work-around or fix.

I'd also like to know the root cause of the problem if possible.

Thanks.  Here is the gdb output:
