https://bugzilla.kernel.org/show_bug.cgi?id=215906 --- Comment #4 from Piotr Piórkowski (qba100@xxxxxxxxx) --- 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. -- You may reply to this email to add a comment.
