Attempting to Get Xen FreeBSD Dom0 working

Hello,

Thanks for trying it out.

However, I’m getting a panic in the AcpiNsWalkNamespace when the Dom0 is booting.  I’m willing and have time to do some testing and poking.  And suggestions or pointers at what to look at next ?

I assume that this box is capable of booting FreeBSD without Xen.

Could you get the file/line number of at least the 3 entries above?

Also, could you paste the full log of Xen+FreeBSD when booted using
boot_verbose? (up to the point of the panic)

Roger.
