Created an attachment (id=402165) --> (http://bugzilla.novell.com/attachment.cgi?id=402165) [details] reduced syslog output (debug kernel)
the server crash after 12:02 without any additional output (Bbug message or similar). I will hunt for more information
Back from vacation... Thanks for the debugging data.

The previous entry was allocated by DRM so that is an obvious suspect of the corruption. It would be nice if we had more messages like this from the debug kernel to confirm this (it could still be a coincidence and something else could corrupt the entry). Anyway, Egbert, could you have a look into this or point to someone who understands DRM / Nouveau?
