Sony have helpfully removed this option from the BIOS with the GRX series
laptops. Sorry if I missed that out from my original email.

I have corresponded with a freebsd user of a GRX570 sony laptop (mine is a
GRX 416), who also appears to be suffering from the kernel panic on boot
when using the 'option PNPBIOS'.

I must admit that debugging this kind of thing isn't my area of expertise,
but if there is anything I can prod at my end to help solve this problem,
I'm willing to try it.

Given this small sample of 2 :) I would guess that it might be a problem
with the GRX range than something specific with my laptop, so it probably
makes sense to get to the bottom of it.

I've tried the kernel source from 4.7, -current and -stable all with the
same results. It looks like pnp support is built into the -stable kernel
by default, as that panic'd with a generic kernel build.

One thing I can try is an earlier kernel, the freebsd 4.3 one is one that
I have to hand.
