linux-lts: black screen after resume
I am running latest-stable. After upgrading linux-lts to 5.4.8 suspend/resume does not work as expected: screen remains black, i can only switch off my laptop and reboot. I can confirm the same behavior with linux-lts-5.4.12.
Downgrading to 5.4.6 and rebooting fixes the issue.
