--- Comment #14 from taijian@posteo.de --- Yeah, screw this.
I tried again, but because there are several different bugs interacting and screwing up the boot process, I really can't seem to be able to figure out which one exactly is borking up which build.
I've been waiting for more than a year to be able to use my laptop the way it was meant to be, and I'm now ready to declare that I'm never again buying a piece of hardware that hasn't already been confirmed to work with Linux.
