unfortuantely, it's not obvious to me which memmove is triggering
this panic.

are you by any chance using an ancient 9load?
i've only seen this problem when upgrading the kernel but not
9load on very old machines that had had a 9load & kernel that
loaded at the mips-inspired 1<<31 (0x80000000). newer kernels
have a KZERO of 0xf0000000 and aren't compatable with ancient
9load. however, new 9loads are compatable with ancient kernels.
