Excellent, thanks. Are you able to find out which minor release 5.6.N
the problem started in? Once we know the number it is sometimes easy to
identify the code change that caused it.
Please also test some current kernels like 5.11 and 5.12 to be sure it's
not something that's already been fixed.

Title:
[amdgpu] kernel crash when resuming from automatic suspension to RAM
Status in linux package in Ubuntu:
Incomplete
Status in linux-hwe-5.8 package in Ubuntu:
Incomplete
Bug description:
Automatic suspension causes the system to freeze on resume. This
doesn't happen if I suspend it manually by opening the system menu and
pressing the suspend button. Suspension works flawlessly when it is
triggered manually.
When the system resumes from automatic suspension, the lock screen is
visible but does not respond. It's frozen. A notification says
something like "system will suspend shortly due to inactivity". It
never goes away.
The keyboard responds during this (at least for a while). The CAPS
LOCK LED turns on and off as I press it (with no delay). Sometimes I
can even switch to another TTY and kill the X server, which is why I'm
reporting it against gnome-shell. When switching TTY is impossible, I
use the "REISUB" combination to shut down. Either way, I always lose
the running session.
This is reproducible about 60% of the time. Eventually I ended up
disabling it and relying only on manual suspension.
