Well, your stack is way off in the weeds and so is your instruction pointer,
so I'm not sure what else you can do there. It's executing a string, so
little surprise that it eventually faulted:

There haven't been a whole lot of changes. My guess would be the recently
added smbios support. You can probably just comment out the call to
smbios_detect() in sys/boot/i386/loader/main.c as a simple test for that. It
could also possibly be the multiple console support in which case it would be
easiest to just step your sys/boot tree back using CVS. The good news is
that sys/boot is largely self-contained so you can step it back while keeping
the rest of the tree up to date for testing purposes at least.
