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(). --lyndon
