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. -Douglas To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
