I'll get back to you if I manage to bisect it. Bisect will definitely be welcome. But first, please try adding the patch that Niklas mentioned above: https://lore.kernel.org/linux-ide/20230913150443.1200790-1-nks@xxxxxxxxxxx/T/#u If that fixes the issue, we know the culprit :) > > Cheers, > -- David -- Damien Le Moal Western Digital Research
