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/* for 4.18.17

I've closed and opened the lid several time, and the laptop woke up each time. Will continue testing. 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 This is a bit of an old bug, do you still have problems? Currently running 5.17.x with no issues. |
Created attachment 279191 [details] 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.
