I'm now using Ubuntu 21.04 hirsute, and this bug can no longer be
reproduced :) Kernel 5.11.0-25-generic.
I've done 3 tests. No crashes so far.

apport information
** Tags added: apport-collected
** Description changed:
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
** Tags added: regression-release
** Summary changed:
- [amdgpu] kernel crash when resuming from automatic suspension to RAM
+ [amdgpu] kernel crash when resuming from automatic suspension to RAM (started
in 5.7.0, not in 5.6.19)
** Changed in: linux (Ubuntu)
Status: Incomplete => New
*
Kernel 5.6.19: OK
If I'm not mistaken, this was the last version before 5.7, so the bug
must have been introduced in 5.7.0.

Title:
[amdgpu] ker
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.
I've finished the tests, here are the results:
5.0.0: OK
5.4.0: OK
5.6.0: OK
5.7.0: BUG
5.8.0: BUG

Nevermind, I was running 5.8, not 5.0.0. I forgot to select 5.0.0 in the
boot menu.

I was able to reproduce this with kernel 5.0.0 too. Isn't it possible
that this is not caused by the kernel? I don't think I had this issue
back then - it's something more recent.

Yes the problem appears to be crashes in the amdgpu kernel driver so
please try some other kernel versions and tell us which have or don't
have the same bug:
