Hi, I found that the domain was crashing because of trying to boot a freebsd 6.1 amd64 kernel ... an i386 kernel kind of gets a little further, until: rlphy0: <RealTek internal media interface> on miibus0 rlphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto re0: Ethernet address: 00:60:e0:e1:21:d7 re0: diagnostic failed, failed to receive packet in loopback mode re0: attach aborted due to hardware diag failure kernel trap 12 with interrupts disabled Fatal trap 12: page fault while in kernel mode fault virtual address = 0x74 fault code = supervisor read, page not present instruction pointer = 0x20:0xc066dd41 stack pointer = 0x28:0xc1020a54 frame pointer = 0x28:0xc1020a58 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = resume, IOPL = 0 current process = 0 (swapper) trap number = 12 panic: page fault Uptime: 1s I'm gonna try to boot a 6.0 freebsd, to see if it is something related to the drivers in the distribution or what.
