dmesg log

System Environment:
Motherboard: Asus Z170-DELUXE
CPU: Intel i7-6700K
BIOS: 1001
Kernel: drm-intel-nightly: 2015y-10m-13d-15h-47m-52s UTC integration manifest

The monitor is connected via a HDMI-to-DVI cable to the HDMI 2.0 port on the motherboard. HDMI 2.0 is provided by the motherboard with an on board DP to HDMI 2.0 adapter.

When waking the display after a several hour idle period, I get a warning in dmesg (full log attached). The display had been powered off for several hours and was turned back on just before the warning.

The SKL DMC firmware is installed from linux-firmware git:

Comment 1 Joseph Yasi 2015-10-18 18:51:07 UTC

This was followed by another warning in intel_uncore.c about unclaimed registers when triggering DPMS again after getting the first warning.

Comment 2 Imre Deak 2016-03-18 15:04:33 UTC

Could you check the latest drm-intel-nightly kernel. The CSR warnings should be fixed there.

Comment 3 Joseph Yasi 2016-03-18 15:29:35 UTC

I haven't been able to trigger this bug in months, so I presume it's fixed. I  never saw it with 4.4.x.
