Boot failure netbsd-9

[bch <brad.harder%gmail.com@localhost>]

I have a system tracking netbsd-9.

I recently rebooted it (after ~30-some days uptime) w latest kernel, modules, userland and it faults before completing boot.

To my eye it looks to be intelfb/drm/kms related, but I’m not certain, haven’t been able to work around it yet.

Here’s an initial select transcription of the kernel log and trace:

...
