Can't toggle power to disk using Linux 6rc3

Open emsaks opened this issue 3 years ago • 4 comments

I've been using uhubctl to toggle power to frozen/hung disks. But now, under Linux 6 (rc3) if the disk is opened (e.g. a process is reading it, or in my case, dmsetup has a dependency on it) the command will hang until the disk is closed. (I've also tried using the sysfs-disable branch).

@mgrzeschik, @hnez would know more why it broke in Linux 6 rc3.

How can I contact them (or will they be notified by the @ mention)?

I guess. I recommend to use older Linux kernel for now. Using Linux 6 is living on the edge at the moment.

I for now can not see what change could have introduced this behavior. This could also be an issue with some specific peripheral/controller driver. At least I can say that the patch introducing the /sys/bus/usb/devices/.../<hub_interface>/port<X>/disable sysfs property is not involved in this. :)

@emsaks, now that #450 is merged, can you try this again - build uhubctl from master branch?

Closing for inactivity. Please feel free to reopen if you have anything to add @emsaks

mvp avatar Sep 25 '22 18:09 mvp

Did you use the latest version of uhubctl to trigger this. Including the recent changes of #450 that was merged lately?

mgrzeschik avatar Sep 29 '22 14:09 mgrzeschik

No; I built your tree myself before the merge.

emsaks avatar Sep 29 '22 16:09 emsaks

Can you try building it from master branch and check if it works for you @emsaks?

I'll try when I can. I've downgraded to an earlier kernel in the meantime...

Thanks anyway! BTW, official kernel 6.0 was released few days ago.
