A quick printf hack says ureg->pc = 0xffffffff801103b3 mostly
(>99.9%), but a few other oddballs are:

  cpu0  0x2400c8
  cpu0  0x226df6
  cpu0  0xffffffff80208b1c
  cpu0  0xffffffff802083f9

etc.  During boot I see complaints from cpu1, but once the machine is
fully booted only cpu0 spits messages.

This is from a generic Dick Tracy amd64 kernel, with a U->pc printf
added to lapicerror().
