Description Juergen Gotteswinter 2013-03-06 15:50:00 UTC 
Trying to Install a 9.0 or 9.1 FreeBSD Guest on a Linux KVM Host ends
in the following error message directly after the Boot Menu:

kernel trap 12 with interrupts disabled

Enabling Verbose does not show more Information.

Tried to set hw.mca.enabled=0 and disabled acpi, without effect. Tested
FreeBSD 8.3, which works when setting hw.mca.enabled=0.

It seems like this Bug is initially triggered by the Qemu -cpu Parameter,
when "-cpu Opteron_G4" is set, this Bug happens.

How-To-Repeat: Try to Install a FreeBSD 9.x Guest on a Linux KVM Host with qemu Parameter
"-cpu Opteron_G4"

/usr/libexec/qemu-kvm -S -M rhel6.3.0 -cpu Opteron_G4 -enable-kvm -m 4096 -smp 8,sockets=2,cores=4,threads= ....

-HEAD shows the same Problem. So far only 8.x seems to be fine.

this still stay with FreeBSD-12.0-CURRENT-amd64-20180315-r331001-disc1.iso under Ubuntu 18.04 X86_64(Linux lxn550jk 4.15.0-10-generic #11-Ubuntu SMP Tue Feb 13 18:23:35 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux).

Ubuntu package info:
qemu-system-x86 1:2.11+dfsg-1ubuntu4  amd64 QEMU full system emulation binaries (x86)

I have try some tips from https://forums.freebsd.org/threads/freebsd-10-does-not-boot-kvm-kernel-trap-12.47409/ but it still not works.

I guess I'll take this one, then. =) It'd be nice to know exactly what change we made to unbreak this, but I don't know that I care enough to ask you to bissecting it.
