Hi!
Here is a new patch to based on HEAD r279508:
https://people.freebsd.org/~dumbbell/graphics/drm-update-38.i.patch
You can apply it to a Subversion checkout using the following command:
svn patch drm-update-38.i.patch
There are few changes:
o The panic reported by J.R. Oldroyd is fixed, but not the CP init
problem.
o A lock assert was added, suggested by Konstantin Belousov
I had several panics ("Stray timeout") with a taskqueue used by TTM, but
it didn't occur in the past 6 days. Maybe it was a problem outside of DRM.
I would like people to test again and report :) If something fails,
please post a full dmesg, taken after loading the relevant *kms module,
or the core.txt.$N file if it's a panic.
Hans Petter and Ed, I couldn't reproduce neither of your problems (HDMI
hotplug events storm and VT-switch misbehaviour). However, they both
involve callouts, like the "Stray timeout" panic I had with TTM. I
suspect there was a transient problem with callouts in HEAD at the same
time. Could you please test again with this patch and a very recent HEAD?
Thank you to everyone!
