Today I've got another NMI with a Linux guest, but a few things were different:
- the host was fresh after a reboot
- the guest was single CPU
- the NMI happened during boot up of the very first VM

kernel: NMI ISA 2c, EISA ff
kernel: NMI ... going to debugger

Not what causes those NMIs but when they happen they always happen during a
bhyve guest boot...
