i installed via the nvidia-installer bumblebee and did a pacman - Syu after that. Unfortnualy after a reboot, i get a black screen and constantly repeating following message:

[Time] iwlwifi 0000:00:14.3: Unhandled alg: 0x707

I can login via tty and uninstalled all nvidia drivers, reverted the pacman - Syu and tried to denable iwlwifi but i couldnt fix it. Any ideas?
