Ryzen suspend locked
by satur9nine from LinuxQuestions.org on (#59KY6)
I am running:
Ubuntu 9.3.0-17ubuntu1~20.04
Linux version 5.4.0-52
AMD Ryzen 9 3900X
ASUS X570 Prime Pro
When I attempt to suspend my machine about 75% of the time it locks up before entering suspend. The CPU fan continues to run and the power light is full on but nothing is shown on the display. Pressing the power button or keyboard has no effect, only long pressing the power button to power off can exit this state.
Are other people experiencing this suspend problem? Is there any chance a new kernel version will fix this issue or are there any suggested workarounds?
I am running the latest BIOS available Version 2802 from 2020/10/23.
I was also having intermittent lockups while running normally, I use the follow boot options to resolve this trouble: processor.max_cstate=5 rcu_nocbs=0-11
