Just a note, maybe useless.
I own a Huawei laptop, model KPL-W00D with Ryzen 2500U and it suffer this same
bug.
I cannot compile a kernel so, after installing Devuan testing, I installed also
the generic kernel located here:
https://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2021-03-15/amd64/
that is a 5.12.0 RC3 and it includes the upstream patch for this bug.
The patch works but only on cold boots, after a simple reboot the bug turns
back again.
Maybe it's only a hardware problem, maybe a distro fault or misconfiguration, I
don't know, but I felt compelled to report this.
If needed I can give more detailed informations.
