(In reply to Takashi Iwai from comment #11) > At best, could you join to the upstream bugzilla and comment there directly? So far I haven't had any facts to comment upstream. For example yesterday's test: I had no knowledge, were I testing patch in https://bugzilla.kernel.org/show_bug.cgi?id=217069#c33 or something else. I just can't guess and comment based on guessing.
