lsmod for 4.18

In 4.19, when I close the laptop lid, the screen turns off, the fan does not spin down; on opening the lid, the screen does not turn back on, and the laptop is pingable, but I can't SSH in. With 4.18, there are no problems. I'm running Slackware current. I have KDE configured to put the laptop to sleep when the lid is closed.

If the network works after resumed, the system should go through a successful system suspend/resume cycle. According to the description, there is a problem in the graphic display. And per the dmesg log in 4.19, the amdgraphic driver has printed quite some warnings, such as 
drivers/gpu/drm/amd/amdgpu/../display/dc/gpio/gpio_base.c:64 dal_gpio_open_ex+0xc/0x30 [amdgpu]

please try blacklist the amdgpu and check if it works.

BTW, please provide the info under
/sys/power/*

After blacklisting the amdgpu driver, sleep works. I've closed and opened the lid several time, and the laptop woke up each time. Will continue testing.
Comment 12 alex14641 2018-11-19 05:01:11 UTC
Tested with the code in drm-next-4.21-wip: with that code, when the lid is closed, the fan spins down; when the lid is opened, the fan spins up and I can ssh in, but the screen stays blank. Also, the following appears in dmesg:

[ 1735.527692] [drm:amdgpu_atombios_dp_link_train [amdgpu]] *ERROR* displayport link status failed
[ 1735.527713] [drm:amdgpu_atombios_dp_link_train [amdgpu]] *ERROR* clock recovery failed
