It seems Lorenzo Pieralisi's cfg space non-posting patches landed in next, so the root cause of this might just be the driver hooking the wrong fault code now. Async and synchronous aborts are different fault codes on ARM. Can you see of removing the "16 +" in hook_fault_code() in drivers/pci/dwc/pci-imx6.c fixes this issue? Regards, Lucas
