ip/rarpd dies as soon as it receives a request.

 rarpd 208: suicide: sys: trap: fault read addr=0xffff0000 pc=0x00002c19

Below is what acid tells me. dofmt:fmt looks bad. This should be equal
to efmt$1, a static format string defined in eipfmt(). I can't figure
out why this looks garbled.

Can somebody please enlighten me?
