I'm running a couple of HVM domU FreeBSD guests under Xen-4.10.1 under a Gentoo Linux host, and have found (frustratingly) that the kernel panics after performing a reboot (after running "make installkernel"). Below is the console output up to the panic:
The kernel config is short and sweet:

For reference, below is the Xen config file:
EDIT: Also of note, I've also tried the unmodified GENERIC kernel config... which was where I started before attempting the custom kernel route. The GENERIC kernel had the same output, so I tried making a custom kernel. Am I missing something?
