Comment 5 for bug 1449438

Can confirm this bug on a Surface Pro 2 with the same Marvel wifi chip (1286:2044) after installing Xubuntu Vivid (clean install, no upgrade).

For me, the wireless connection will be established, but as soon as I start a browser to use it, the system freezes immediately, so there is nothing in syslog.

The Marvel wifi chip worked in Ubuntu 14.10 after downloading latest firmware from Marvel's git and putting it into /lib/firmware/mrvl/.
