Comment 3 Sylvain Petreolle 2014-04-29 01:06:20 UTC 
Please change the version to fc20.
I got this error when connecting an USB drive into Vmware Workstation.
Comment 4 Panormitis Petrou 2014-05-01 05:55:38 UTC 
I can also confirm this bug exist on fc20.
Currently running kernel-3.13.10-200.fc20.x86_64
Comment 5 Justin M. Forbes 2014-11-13 15:58:04 UTC 
*********** MASS BUG UPDATE **************

We apologize for the inconvenience.  There is a large number of bugs to go through and several of them have gone stale.  Due to this, we are doing a mass bug update across all of the Fedora 20 kernel bugs.

Fedora 20 has now been rebased to 3.17.2-200.fc20.  Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.

If you have moved on to Fedora 21, and are still experiencing this issue, please change the version to Fedora 21.

If you experience different issues, please open a new bug report for those.
Comment 6 Justin M. Forbes 2014-12-10 14:58:31 UTC 
This bug is being closed with INSUFFICIENT_DATA as there has not been a response in over 3 weeks. If you are still experiencing this issue, please reopen and attach the relevant data from the latest kernel you are running and any data that might have been requested previously.
