>Synopsis: Dec 15 snapshot made T410 graphics unusable
>Category: kernel
>Environment:
System : OpenBSD 6.6
Details : OpenBSD 6.6-current (GENERIC.MP) #531: Sun Dec 15
02:17:57 MST 2019
[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
After upgrading to Dec 15 snapshot, in my thinkpad t410 image is
so distorted that it's impossible to read the text. This
happens in both, X11 and tty console, so I have to ssh login
from another machine in my LAN to operate (however there are
those who still argue full graphics support in tty console is a
wonderful thing.)
I'm not completely sure, but I think these lines already appeared
in dmesg before this issue happened (I mean on previous
snapshots):
[drm] *ERROR* CPU pipe A FIFO underrun
[drm] *ERROR* PCH transcoder A FIFO underrun
>How-To-Repeat:
Boot the machine and wait till drm is loaded.
>Fix:
I don't know.
