Comment 29 for bug 1956821

I'm experiencing the same issue on GNU/Linux 5.13.0-27-generic x86_64

Hardware is ASUS PN50-E1 / AMD Ryzen 7 4700U with Radeon Graphics

I've been unable to find anything useful in the systemd journal with log levels for systemd and udev both at 9 - the problem seems to be after the journal stops. During the stuck shutdown process, Alt+SysRq+B works and forces a reboot.

I do not encounter the same issue with 5.11.0.27-generic (HWE) nor with 5.4.0.96-generic (latest non-HWE).
