so far the feeling is that -) 3.14 seems to support this drive better, as it appears to be able to retrieve its power status and to, more importantly, set it, unlike the previous kernel (4.4-) -) 3.14 seems to be also more invasive. Previously, hdparm -C would return some error, but never wake up the drive. on internal SATA drives it would just work, and also never wake up the drive. here it seems that if the drive is in standby, the command works as expected, but as soon as it gets into some deeper sleep (not just spun down, but also led blinking intermittently), then the command wakes up the drive that spins up before hdparm returns an output -) udisk2 seems to be doing something too (note: it is also present on 14.04, but it somehow doesn't get in the way in that release). I killed it manually, but at some point it respawned again, and automounted the drive which spun up.
I'm Still working to get the 3.14 on 14.04, but the fear is that it might be multiple things that regressed and might be hard to find. I might have to go back to 14.04, although, given the current Linux situation, i doubt that this bug would get even investigated in the next couple of years.. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1733068 Title: Unmounted USB drives wake up on 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1733068/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
