I rebooted and exactly the same configuration gives now Device-initiated interface power management on for both WD20EFAX. Also tested on 6.8.12, on which Device-initiated interface power management is off for both drives, as before. > I would add some debug prints around: > https://github.com/torvalds/linux/blob/v6.15-rc6/drivers/ata/libata-eh.c#L3512-L3520 Good idea there is something weird going on. > Did you do something with this drive? Nope. > Was this perhaps the drive that got timeout? and for some reason > the timeouts caused DIPM to get disabled? No, no timeouts. > Did you get any timeouts on the other drive of the same model (/dev/sda) ? None!
