Bug Description
System Info
Dell Inspiron 5515
Operating System: Kubuntu 21.04
Kernel Version: 5.12.9-
OS Type: 64-bit
Processors: 16 × AMD Ryzen 7 5700U with Radeon Graphics
Memory: 15,1 GiB of RAM
Graphics Processor: AMD RENOIR
If I suspend my pc, the screen, fans and keyboard backlight turn off. However if I try to wake up from suspension the screen stays black, while the keyboard backlight starts blinking. The only way to unlock it is to click the power button, and the pc will automatically restart (thus losing the data of the active session).
Initially I had the 5.11 kernel, then to see if the problem was solved I tried to install the 5.12 kernel and the 5.12.9 kernel, but there were no improvements.
