Hello all,

after a long journey of google and forums I finally triggered out, what lead to that mysterious errorcode.
With all standard NVidia drivers, i had this error as last message in the Xorg.0.log and some freezing CPU's stuck atr 100%, system not reacting any more.

The main hint was, to step forward to NVidia driver 331. With that one, the error code got translated and speaking now: "Failed to initialize DMA"! Whoohoo, that's finally something to deal with!!!

To solve this, I had to deactivate IOMMU in my motherboards BIOS. The reason was potentially, that this used the same space as the DMA wanted to have, so it didn'T work.

As i struggled several days and quite a dozen of hours now, I thought it's a good idea, to provide this knowledge to the community somewhere, so here it is!

Best regards
QD

Thanks for an attempt at marking the thread 'solved'. Better though to use Thread Tools.
