I've tested suspend / resume with 'linux-image-5.13.0-trunk-686 (5.13.12-1~exp1)' - not working!
Kernel freezes with the same error. Full logs at: https://linux-hardware.org/?probe=04307947ae (dmesg.1 logs for 'task blocked') I'm using Debian 11 clean installation with Debian 10 kernel (Buster, linux-image-4.19.0-17-686). Same configuration Debian 11 with 'linux-image-5.13.0-trunk-686 (5.13.12-1~exp1)' from experimental for testing. -- AK
