Chris, you referred me to this bug as I reported
Bug 90835 - [4.1-rc6] gpu hang: ecode 6:-1:0x00000000, Kicking stuck
semaphore on render ring
I skimmed through it and it appears that there are some patches to test?
But I am not sure which ones these are. Can you or someone else
enlighten me?
Also I note that I still use
Option "AccelMethod" "uxa"
and I have
martin@merkaba:~> cat /etc/modprobe.d/i915-kms.conf
options i915 modeset=1 i915_enable_rc6=7
thus maximum energy saving. But according to powertop it never enters
the highest sleep state anyway.
I will remove the AccelMethod setting now and see whether it helps. If
not, I downgrade to 4.1-rc4 for now, as issues have been at least much
less frequent with it.
And its really that for me 4.1-rc6 makes things much *worse*. I am
typing this after a clean reboot and already got the GPU hang again. It
happens about every few minutes. Are you really sure this is the same
GPU hang? I didn´t have this before 4.1 kernel?
