No problems on a Dell 755, but I'm using serial console, it doesn't have

(I guess the Intel chipset still provides a pckbc, even if it's notwired

to an external connector):

I identified the issue, this patch causes some trouble on my laptop:

http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/dev/ic/pckbc.c.diff?r1=1.44&r2=1.45


I will give tech-kern a try.

Hmm, slight correction.

Relating to this patch, increasing <s> value (from 100 to 1000 forexample) and decreasing the delay() value accordingly makes the dom0boot again.

Any hint what could cause such an issue? Looks like Xen is at faultthere, booting with GENERIC is fine.


Attached is the dmesg output from this laptop.

Cheers,
