<pre>It seems I have the same issue on a several machines with similar GPUs. After
system is started all is ok. But if to leave a machine and wait till display
turns off, after that trying to awake it gives nothing. Display stays black.
And only switching to any of VTs and turning back to VT7 makes display awaken
causing the image appearing. But then in dmesg appears next messages:
[ 143.476015] [drm] GPU HANG: ecode 2:-1:0x00000000, reason: Command parser
error, iir 0x00008040, action: continue
[ 143.476015] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 143.476015] i915: render error detected, EIR: 0x00000010
[ 143.482472] [drm] GPU HANG: ecode 2:-1:0x00000000, reason: Command parser
error, iir 0x00008000, action: continue
[ 143.482472] i915: render error detected, EIR: 0x00000010
After that I tried drm-intel-nightly but it didn't helped: GPU HANG also
appeared after display was turned off. Saved error dump, dmesg, Xorg.0.log,
please, see in attachment.
After that I tried to boot with i915.enable_rc6=0 kernel option. The thing is
that with this option display doesn't turns off at all. And in accordance to it
GPU HANG also not appears.
So. Yes, it still happening on latest drm-intel-nightly and no, with
i915.enable_rc6=0 kernel option it doesn’t happening because display doesn't go
into standby mode.</pre>
