** Description changed: Hello, I found that my system froze during the suspension process since Linux kernel v5.3.0-42. When the display switches to a blank terminal with a cursor on the top- left corner, the system got stuck. Sometimes I was able to switch to a virtual TTY with Control+Alt+[F2-F7], but it got stuck as well within a few seconds. Also, I've noticed that the backlight of my keyboard stays on indefinitely after the system froze, even though I've set a timeout for it to turn off. I've tried the ways to debug system crash mentioned in the Community Help Wiki, but with no luck. But it seems that I was able to connect to my computer via SSH if I was not connected to it before it froze, otherwise the SSH server will freeze as well. After some investigation, I found some information in "/var/log/syslog" that might be useful. I've found that "systemd-sleep[5261]: Suspending system..." was the last message that was logged to that file if the system froze, although there might be one more random or garbage message follow it.
