Comment # 76 on bug 102322 from
Just for the record, since another month has passed: I can still reproduce the
crash with today's git head of amd-staging-drm-next within minutes.

As a bonus bug, with today's git head I also get unexplainable "minimal" memory
and shader clock values - and a doubled power consumption (12W instead of 6W)
for my default 3840x2160 60Hz display mode in comparison to last month's
drm-next of the day:

> cd /sys/class/drm/card0/device

> xrandr --output HDMI-A-0 --mode 3840x2160 --rate 30
> echo manual >power_dpm_force_performance_level
> echo 0 >pp_dpm_mclk
> echo 0 >pp_dpm_sclk
> grep -H \\* pp_dpm_mclk pp_dpm_sclk
pp_dpm_mclk:0: 300Mhz *
pp_dpm_sclk:0: 214Mhz *

> xrandr --output HDMI-A-0 --mode 3840x2160 --rate 50
> echo manual >power_dpm_force_performance_level
> echo 0 >pp_dpm_mclk
> echo 0 >pp_dpm_sclk
> grep -H \\* pp_dpm_mclk pp_dpm_sclk
pp_dpm_mclk:1: 1750Mhz *
pp_dpm_sclk:1: 481Mhz *

> xrandr --output HDMI-A-0 --mode 3840x2160 --rate 60
> echo manual >power_dpm_force_performance_level
> echo 0 >pp_dpm_mclk
> echo 0 >pp_dpm_sclk
> grep -H \\* pp_dpm_mclk pp_dpm_sclk
pp_dpm_mclk:0: 300Mhz *
pp_dpm_sclk:6: 1180Mhz *

But that power consumption issue is negligible in comparison to the
show-stopping crashes that are the topic of this bug report.
