[Qemu-devel] SeaBIOS error with Juniper FreeBSD kernel

[Brandon Bennett <bennetb@gmail.com>]

When booting a Juniper JunOS kernel (FreeBSD based) I am getting a
panic: unkown/reserved trap error immediately after the kernel loads.
If i use an older pc-bios with the '-bios' option everything works so
it seems to be an issue with the SeaBios.

With #DEBUG_BIOS enabled in hw/pc.c here is what i am getting during boot.
