Public bug reported:
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.
