Re: Boot failure netbsd-9

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:

kern info: [drm] failed to find VBIOS tables

I no longer think this is (necessarily) drm/kms issue, but init dies no matter which kernel I’m using: a backup, the original install kernel, or a copy of a an otherwise working rescue kernel...

Anybody else seeing this, or remembering anything from the last 30 or so days in netbsd-9 cvs that might correspond?
