This caused a regression on APUs that do S3; please pick up https://gitlab.freedesktop.org/agd5f/linux/-/commit/8cf1a5e7e7ab6532beaa14b03bb5bf838be906e0 as well to avoid it

This bug is awaiting verification that the linux-oem-5.14/5.14.0-1021.23 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
