Description DaKahuna 2013-03-09 15:00:16 UTC

I am having the same issue as reported in UBUNTU bug reported in 
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1094534

I am running a Samsung Ultrabook NP900X4C. 

Bug was discovered when all USB 3 devices were found not working after laptop was taken out of suspend mode.  kernel module xhci had failed.  /var/log/everything/current reported:

USB can be re-activated by rebooting the system until it goes into suspend mode and then the USB 3.0 stops working again.  USB 2.0 port unaffected by this issue.

Comment 3 Alan 2014-04-09 15:46:39 UTC

3.14 contains a lot of xhci fixes - is this still a  problem ?

Comment 4 devsk 2014-04-09 17:11:38 UTC

I think this bug is just duplicate of https://bugzilla.kernel.org/show_bug.cgi?id=30912. Same behaviour of /dev/sdX becoming /dev/sdY after resume making all mount points invalid.

I haven't tried 3.14 yet. Unless there is some specific fix for 30912 which addresses the re-numbering of the device after resume, I am not willing to try anything new because its a lot of work and I have seen my hopes dash in last 6 months many times. Its like shooting in the dark. I don't think any developer has analyzed 30912 and done anything to fix it.

Comment 5 devsk 2014-04-21 21:54:42 UTC

Finally, updated to 3.14.1. And same old same old. /dev/sda becomes /dev/sdc after resume and all hell breaks loose.

Comment 6 devsk 2014-04-21 21:55:58 UTC

I think this bug can move out NeedInfo now that information has been provided.
