So I found out what was going wrong. The solution turned out to be pretty straight forward, I just had to add
Option "ForceEnablePipA" "true" to my xorg.conf. I tested this with the driver form unstable (2.2.0.90-3) and git master branch. No more crashes since yesterday. As requested in the intel man page, I filed a bug upstream about this: https://bugs.freedesktop.org/show_bug.cgi?id=14521 Seems I should read man pages more often... Sorry to have bothered you and thanks for the great support. Regards, Soenke -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
