Thanks, applied. I modified the commit log a bit to mention the possible commit causing this: commit 82d7aba71541a308bc19e869f7cf7423672dee37 Author: Rajkumar Manoharan <[email protected]> Date: Fri Oct 10 17:38:27 2014 +0530 ath10k: fix kernel panic while shutting down AP Based on GFP flag given to DMA coherent allocation, the behaviour of dma_free_coherent is changed. This behavioural diffrence is noticeable in ARM platform. If DMA memory is allocated with GFP_KERNEL, free coherent can not be called inside spin lock. This is causing kernel crash in ARM platforms. Fix this by changing GFP flag to atomic. This is most likely a regression from commit 64badcb6d645 ("ath10k: workaround fw beaconing bug").
