Over the last view months I’ve been experiencing an intermittent issue with suspend. About 1/10-20 suspends, the system will physically wake, but there will be no display and from what I can tell, I am unable to use
CTRL+ALT+<F key> to drop to TTY (though I may just not be seeing it). The displays don’t ever behave this way on Windows in testing.
I am not seeing any errors relating to
AMD Ryzen 5 2600
Asus B450i (latest BIOS)
RX 580 (amdgpu)
Fedora 33 + Cinnamon (Xorg)
NOTE: The issue has been happening for a few months across several kernel versions. I noticed the system hung as described this morning when waking it. Yesterday I ran an upgrade, but I’ve suspended the system several times since the hang this morning and it’s worked fine, so it’s still intermittent.
