Created attachment 419060 [details] iwlwifi-cancel-scan-watchdog-in-iwl_bg_abort_scan.patch
Test kernels w/ above patch building here: http://koji.fedoraproject.org/koji/taskinfo?taskID=2225224 Give them a try? Can you replicate the problem with those kernels?
I will try and report what are the results.
Ping? Koji won't keep those test kernels forever...
After more suspend/resume cycles I can confirm that kernel from http://koji.fedoraproject.org/koji/taskinfo?taskID=2225224 fixed this bug.
Many thanks!!

FWIW, to me that appears to be a different issue.
