--- Comment #7 from Christoph Haag haagch.christoph@googlemail.com --- Created attachment 219231 --> https://bugzilla.kernel.org/attachment.cgi?id=219231&action=edit dmesg with gpufault R600_DEBUG=nodma
I can not confirm it 100%, but I think R600_DEBUG=nodma helps.
So far the unable to handle kernel paging request did not happen with R600_DEBUG=nodma. I only got a GPU fault (playing csgo with nine), maybe unrelated, dmesg attached.
