Public bug reported:
After update from kernel 4.2.0-18 to 4.2.0-19, my wifi got broken and
the video driver had some problems too, because my resolution was
downgraded to 1024x768. Boot startup screen was changed from a graphics
mode to a low resolution text mode (25x80 maybe).
I had to boot back to 4.2.0-18 to report this bug. Please let me know
what extra information is needed.
