Hi John,

I was discussing this with peter on chat:
<peter> anders: what OS release?
> peter: FreeBSD/amd64, RELENG_5_4.
<peter> anders: this is sounding like irq0 / 5.x problems
<peter> ahh
<peter> anders: bug jhb to mfc the fixes for this. Its a
known problem and already fixed.
<peter> panic: Can't find ExtINT pin to route through!
<peter> in other words, the routing of irq0 is fubar.
<peter> a mfc of the apic timer code would 99.99% likely solve it
just like that.
> peter: Mind you I am using RELENG_5_4, not RELENG_5.
<peter> anders: FreeBSD is the only known OS on the planet that
uses irq0 for a clock source in SMP mode. Hence we are the people who find all
the problems in the untested bios code and hardware. Hence we switched
from the irq0 timer to local apic timer to do it like everybody else
It happens with FreeBSD/amd64 running RELENG_5_4 using options SMP. I
can boot if I set hint.acpi.0.disabled=1, but then the OS does not do
SMP and apic things etc.
Do you have a patch to fix this? Will you MFC it?
