reply #8,

Could you dump the eDP PSR status?
# cat /sys/kernel/debug/dri/0/i915_edp_psr_status

Have you tried the driver parameter "options i915 enable_psr2_sel_fetch=0"? Does it work for you?

The patch is created by applying quirk for Dell machine [1], I'd like to check if it indeed take effect on your platform, could you dump lspci output by
$ lspci -nnvv
