Well I guess there's more than one way to skin this cat.  I
disassembled the whole of vmlinux and found the code:

c05fe934 <__error>:
c05fe934:       e1a00000        nop                     ; (mov r0, r0)
c05fe938:       eafffffd        b       c05fe934 <__error>

Of the two call sites, it seems most likely to be a failure in
__lookup_processor_type.  Unfortunately the exact error message is not
shown, but at least I can adjust the addresses and breakpoint it now.
