Description Adam Williamson 2017-01-26 15:20:43 UTC 
Description of problem:
This occurred in openQA testing of Fedora-Rawhide-20170125.n.0. This
kernel warning showed up in the test that boots the Workstation live
image and checks if there are any unexpected notifications; all it does
is boot the image, sit at the desktop for ten minutes, then check for
notifications. The test is run in a qemu VM with qxl graphics.

Doing some pruning, this bug looks to be several kernel versions old. Please test on a newer kernel and reopen if the problem still exists.
