I tried bisecting on the upstream kernel and it turns out that the problem al= so 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 kern= el that I stopped seeing the problem. --=20 You may reply to this email to add a comment.
