Right, so I saw the oops below while playing with the driver earlier but I attribute it to the fact that radio was switched off in the BIOS (rfkill show said "Hard blocked: yes" for the wireless device). After changing that I'm running smoothly so far. I'll keep you posted if I see anything while using it in the next weeks. Thanks. -- May 4 18:27:20 gere avahi-daemon[976]: Withdrawing workstation service for wlan0.
