--- Comment #2 from Alex Deucher (alexdeucher@gmail.com) --- The amdgpu acpi handling hasn't really changed in ages. If this is new for 5.13 can you bisect?
https://bugzilla.kernel.org/show_bug.cgi?id=213201
--- Comment #3 from Erhard F. (erhard_f@mailbox.org) --- As I bought this machine just recently I can't tell. But I will try to bisect.
I got this Kaveri-based one instead of the Excavator-based one from bug #211875. With bug #211875 it was not fit for it's purpose unfortunately so I sold it again. This Kaveri-based one here fares much better. Only this memory leak but no grave issues otherwise.

--- Comment #4 from Erhard F. (erhard_f@mailbox.org) --- Happens on 5.11.x and 5.10.x too. This may take a while...

Bisecting was no success, but I traced the memory leak back to kernel 4.4.x series.
Kernels v4.3.6 and v4.2.8 won't boot on the machine. But probably the leak has been there since amdgpu got first introduced in kernel 4.2 anyhow.
