Hi Guys, Just a note that may be helpful for tracking this down here is what I found out lately.
If in "drivers/net/wireless/marvell/mwifiex/cmdevt.c" file, "mwifiex_cmd_timeout_func(struct timer_list *t)" function I comment out these: //if (adapter->if_ops.device_dump) // adapter->if_ops.device_dump(adapter); //if (adapter->if_ops.card_reset) // adapter->if_ops.card_reset(adapter); The wifi will still drop with the timeout command but at least the mwifiex_pcie module wont freeze and so you will be able to restart or even put the pc into sleep and after a resume simply continue where you left off without having to do a hard restart by long pressing power button. It seems the card_reset(adapter) function is the one freezing the module and so freezing the wifi, so will try to see what's there but if any of you have any idea how we could reset the adapter and even (just for testing why not) always reload the firmware and see if that fixes it as it seems the resume does the same thing and that makes things work again.
