--- Comment #4 from Piotr Piórkowski (qba100@gmail.com) ---
I've misled you a bit by saying that the bug didn't occur on the 5.13 kernel. I
tried bisecting on the upstream kernel and it turns out that the problem also
occurs on the 5.13 - I build it using ubuntu default config from kernel
5.15.0-27.

So far, the only kernel build I haven't noticed a problem with (excluding
kernels 5.4 from Ubuntu 20.04 LTS) is kernel 5.13.0-28-generic form Ubuntu.

Interestingly, I found the sources of this kernel on git kernel.ubuntu.com and
built this kernel using this config from kernel 5.15 and the problem also
occurred.

It was only when I built this kernel using the default config for this kernel
that I stopped seeing the problem.
