I'll try the latter.
In the mean time, the diagnostic kernel panics as follows:
root file system type: ffs
init: copying out path '/sbin/init' 11
kernel: double fault trap code=0
Stopped in pid 1.1 (init) at netbsd:Xintr_legacy7+0x48: movq %r9, 0x28(%rsp)
so you guess about interrupt 7 is probably right.
If I disable acpi (but not ehci), it boots, but the nfe driver emits
'watchdog timeout' and there is no network.
Hope that helps.
