It happened again ~90min after doing a `systemctl kexec` and using `ryzenadj`,
so I can better answer your questions.

It seems to differ from bug 218305 in that the values `ryzenadj -i` returns
seem sane on my machine, whereas in the other bug report they weren't. I'm also
getting the correct reporting for the maximum supported frequency for all of my
cores.

I can't say what triggers it, but I've noticed it most when using the machine
for a couple of hours, sometimes while using the processor moderately but not
excessively.

This time it happened with the performance governor. 

I added an attachment with the output of ryzenadj, cpupower and sysfs taken
while the machine was stuck at 400MHz
