"wait timed out!" in dmesg
We have an ASUS X570ZD laptop equipped with AMD Ryzen 7 2700U with Radeon Vega
Mobile Gfx and NVIDIA GeForce GTX 1050 Mobile.
We tried with Linux kernel 4.18.3.
After system resumes from suspend, there is a prompted picture for a short
time, then system goes no display for a long time.
After the long time, system turns off the display's backlight. User must
presses any key to have the login screen.
The resume process is not smooth and hits the error:
[drm:hwss_edp_wait_for_hpd_ready [amdgpu]] *ERROR* hwss_edp_wait_for_hpd_ready:
wait timed out!
We have the dmesg with amdgpu.dc_log=1 and drm.debug=6
