Anyways, we have a virtually identical hardware with a Marvell SD8688 based wireless module, which uses the libertas driver. Running kernel 3.10.41 we have no problems for 50 days. Running the same kernel with mwifiex with the SD8788 we see a freeze which requires a hw-reset within about a day. Similar to the most recent kernel. Are there known sdio issues with SD8788? Will try to get useful information from the mmc system.. Regards, Florian
