The problem is already solved, it was crashing because blkback in Dom0
was not correctly working -- nothing to do with FreeBSD. The 9.x
releases work correctly, the problem is with HEAD and the backtrace I've
posted. BTW, if you wish to try HEAD you will need the ELFNOTE patch
I've posted and boot with "hw.mca.enabled=0" to get to the panic I've
posted earlier.
