I know it's a pain on a laptop, but if it is at all possible to = capture either a verbose or non-verbose dmesg that would really help = narrow it down. Also, if anyone can try reverting just the MADT-related changes in the = recent Xen changes to see if you can narrow down which exact one = triggers the panic that would be really helpful. --=20 John Baldwin
