OK I have to go now but I managed to get this working without the issue coming up. At this point I am not sure if all of these are required but I cherry picked 2 patches from wireless-testing and then added 4, one based on sujith's suggestion. http://bombadil.infradead.org/~mcgrof/patches/pm-stuff/0001-mac80211-fix-resume.patch http://bombadil.infradead.org/~mcgrof/patches/pm-stuff/0002-mac80211-fix-WMM-AP-settings-application.patch http://bombadil.infradead.org/~mcgrof/patches/pm-stuff/0003-ath9k-set-and-restore-ps-prior-to-stop-and-interface.patch http://bombadil.infradead.org/~mcgrof/patches/pm-stuff/0004-ath9k-ensure-hardware-is-awake-during-ampdu-TX-actio.patch http://bombadil.infradead.org/~mcgrof/patches/pm-stuff/0005-ath9k-synch-TX-DMA-buffer-upon-TX-cancelation.patch http://bombadil.infradead.org/~mcgrof/patches/pm-stuff/0006-ath9k-do-not-wake-up-device-if-it-hasn-t-been-starte.patch Its likely only patch 3, 4, and 6 are the only ones required. In fact maybe even 6 will fix it, but I just gotta go so cannot test that. I was able to resume about 10 times consecutively which I was unable to do before.
