@halfbyte sounds like issues with the power saving. AFAIK the linux power saving for laptops is primarily based on ThinkPad notebooks. And even there, these glitches occur. AFAIR you have to exclude these parts from the power saving profile, sometimes even to go so far as to disable the hardware-based power cycles.
@ginsterbusch Sounds reasonable. Do you know any good resources on how to tweak this stuff? I'm more or less a Linux n00b of the highest order when it comes to hardware tweaking.
@halfbyte @ginsterbusch I basically just prepend all my search queries for Linux questions with "arch" and then wiki pages usually show up first. Like e.g. https://wiki.archlinux.org/index.php/Power_management
