I think as you expected, got yet another panic, however at a different place. Panic summary here. Full console messages below … and for reference, also included the full boot messages from the same kernel booting the bare metal. > > Let know what you are thinking as the problem … I can certainly do some more poking and trail and error stuff on my own as well, but just need a bit more information and guidance.

I don't have a system with this specific ACPI configuration to trigger this, but I have the following patch, which _might_ solve your problem: https://people.freebsd.org/~royger/xen_acpi.patch Again, it should be applied on top of your already patched pvh_dom0_v8 branch (don't remove the previous patch). If this doesn't solve your problem I will try to find a similar box so I can reproduce the issue. Roger.
