Technically, you can debug your real machine kernel using serial (aka com) port, but I do not think you need to do that. When your kernel panics, it takes your to ddb, right? You got "uvm_fault page fault trap": it means kernel tries to access some invalid memory address. It happens in

Rupert, that's a great article, thanks for sharing. I don't see how that helps when my OpenBSD host machine would crash (not the QEMU guest) when I so much as touch the track pad. On Sun, Apr 15, 2018 at 2:05 AM, Rupert Gallagher wrote: >

OpenBSD 6.3 kernel panic

Hi all, I searched the mail archives briefly but couldn't find a related issue. Apologies if this is a duplicate. Since upgrading to OpenBSD 6.3 on my amd64 laptop, it has been crashing whenever I touch the track pad. Touching the track pad after X starts generally causes the machine to just
