--- Comment #41 from Simon <sur3 at gmx.de> ---
Ok seems there is an artefact for a few milliseconds when switching back from
text terminal to graphical terminal but the major GPU hang seems fixed. ^^
Also getting some new Errors in dmesg, but that seems not to be a real problem,
because everything seems to work so far..
