If this is a regression, can you bisect?  https://www.kernel.org/doc/html/latest/admin-guide/bug-bisect.html

I don't know. This is a new machine and have seen this since 5.10.x which was the first kernel I tried on it.

dmesg (kernel 5.12-rc5, A10-9700E)

Gave kernel 5.12-rc5 a try but the issue stays.

Looks like I really need to find an older kernel where this does not happen and start a bisect from there. This will take some time...

dmesg (kernel 4.14.228, A10-9700E)

Traced the issue back to kernel v4.14.228 which is still affected (v4.19.184 and v5.4.109 too). On v4.14.228 no stack trace like in recent kernels but these messages:

[...]

[28547.409986] cz_send_msg_to_smc_async (0x002f) failed

Apart from that the machine behaves the same after these "cz_send_msg_to_smc_async (0x002f) failed" - CPU permanently downclocked to 800 MHz, desktop 'freezing' issues with display going black after some time. Access via ssh still works.

Sorry but my bisecting efforts came to a halt. Last kernel I was able to boot was  4.14.228. And this one still has the issue.

Kernels 4.13.16, 4.12.14, 4.11.12, 4.10.17, 4.9.264 I was able to build but they don't boot into desktop or even console. Just getting a "no signal" message von my monitor after the kernel has booted, and some of these kernels do a reboot.

Don't know how to proceed from here.
