I don't think it is an "amd on intel" issue - it is probably the stack trace dumping code wrongly finding the init_amd symbol due to CPU_SUP_AMD bring compiled in or so...
Rather, it looks like the issue is what Steve said.

Well, if you have a 64-bit cpu, you could consider running a 64-bit kernel for many reasons. The most important one being that 64-bit code is enjoying orders of magnitude more testing because the world has moved to 64-bit already. -rt included.
