Title: Marvell 88W8797 wifi (module mwifiex) does not work on Surface Pro Status in linux package in Ubuntu: Confirmed Bug description: I've been running Ubuntu 14.10 on a Microsoft Surface Pro. After some initial problems (see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1165938) (fixed by kernel updates I guess) the wifi was working fine. Since the upgrade to 15.04 the problems are back: I can connect to a wifi network, the connection is working for a few seconds but drops right after. I attached the relevant entries in dmes.log. I tried installing the marvell firmware from git://git.marvell.com /mwifiex-firmware.git, that didn't change anything. I also tried the mainline kernel from http://kernel.ubuntu.com/~kernel- ppa/mainline/v4.1-rc1-vivid/: the connection is again working for a few seconds but the whole system hangs afterwards.
