Version-Release number of selected component (if applicable):
I have not attached the dmesg as it contains only the text pasted above at this point.
Steps to Reproduce:
1. boot the rawhide kernel on similar hardware
This bug appears to have been reported against 'rawhide' during the Fedora 25 development cycle.
Changing version to '25'.
