--- Comment #12 from Filip Wattos@gmail.com 2011-11-08 02:35:35 PST --- Thanks for the input.
At this moment I have reinstalled the open source drivers and it seems stable now. I have tried using catalyst and maybe that has caused issues (as catalyst apparently overwrites the mesa libraries).
If I dont experience any hard freezes anymore, I will close the issue.
