HP Envy X360 15-en0000na laptop runs kernel 5.11 without problems until the machine is shut down. This seems only to occur on machines with AMD Ryzen CPU. My Intel machines do not have this issue with kernel 5.11. If shutdown is requested from within the plasma desktop, or if only using a VT console and the command "systemctl poweroff" or "systemctl halt" are issued, then the system shuts down but immediately reboots again, and will not remain powered off or halted. This is a high severity regression, since all kernels 5.10.x do not have this issue.

Additional info:
* package version(s) Kernel 5.11 currently in testing

* config and/or log files etc.
* link to upstream bug report, if any

Steps to reproduce:

Update kernel to 5.11, and boot. Then try to shutdown or poweroff - the system will shut down, but immediately reboot - so the only way to power off is to press and hold the power button for an unclean power off which is highly unsatisfactory. Perhaps 5.11 will not be pushed to the repos until the upstream bug is fixed?
This task depends upon

With a lot of help with building bisect kernels from loqs a kernel bisection has been completed identifying the first bad commit, and this is reported on the upstream bug at:

Hopefully a solution will be found as a fix for the bad commit.

linux-5.11-arch2-1 has the fix from and another fix from and is currently in the [testing] repo. I have installed and tested this kernel and it fixes the shutdown going to reboot instead of poweroff, for me. So with these new patches the issue is fixed for me.

This is resolved in kernel 5.11.3 for me.
