And there is no output at all with dmesg, just as if nothing happens. Downgrading to 5.17.9 let the cpu stay steadily with 0.8G in the same situation. But who knows if this is something related to this subject at all? Anyway, I wonder why I miss any kernel messages. -- You may reply to this email to add a comment.
