Thinkpad T14s (Gen 1) AMD Ryzen CPU. Upgraded to 21.10 from 21.04,
Computer fails to enter sleep when suspend timer elapses. e.g. on battery computer should suspend after 10min, on AC should suspend after 30 min, but in both cases the screen is off but the computer did not successfully enter suspend (bios is set suspend into S3. there is a huge thread over at lenovo about support for amd for S0. Haven't tried it yet because there are some things that aren't in 5.14 only in 5.13)
The screen does not turn back on after a failed suspend. This happens with both built in screen and with external display.
The computer enters (and exits) sleep without issue if it is done manually e.g. by closing the lid.
EDIT: looks like there is a segfault in
