[Xen-devel] still more excruciating pain booting FreeBSD on top of trunk

[Kip Macy <kmacy@xxxxxxxxxxxxxxx>]

It looks like I have to scrutinize the linux domain builder a little
more closely.

I just panicked DOM0 by running it on a freebsd image with BSD_SYMTAB in
it:

(XEN) (file=sched_bvt.c, line=312) Get domain 3 bvt mcu_adv=10,
warpback=0, warpvalue=0, warpl=2000000000, warp
