The current drm and radeon drivers work on every card that I > have, which in the r600 class are HD 3650,3850,4650. I think the variable include more than just the model of graphics card. I just replaced my motherboard, keeping all other components, disks, software and configuration. With the old motherboard my HD 3650 was working great including 3D acceleration. With the new board, X will hang/crash with DRI enabled. Even with DRI disabled, I still experience problems with the screen not updating unless I wiggle the mouse. The new mother board is an ASUS P5E3 Pro with an Intel X48 Northbridge. The severity of the hang requires a hard reset (fortunately ZFS is resilient!). No xorg log file is generated/preserved, nor is it possible to break to the debugger. I do not have a serial console. This makes it difficult to debug. What could I do to shed more light on this situation? Cheers, -- Norbert Papke. npapke@acm.org
