3.13-rc kernels boot fully with X running but no graphical screen and it freezes in VC with not all the startup messages displayed but I could ssh in from another box to check dmesg and logs.
Xorg.0.log which I thought I had saved did not log an error.
dmesg said "nouveau Playlist update failed".
Changed the GeForce GT 560 Ti for a GeForce 8600 GT and 3.13.0-rc6 is up and running.
If necessary I can go back to the GT 560 Ti to gather dmesg and Xorg log information.
Having a dmesg would be nice. One thing I can think of off-hand is that 3.13-rc has MSI turned on by default. You can turn it off by adding "nouveau.config=NvMSI=0" to your kernel cmdline. If that doesn't help, a bisect restricted to drivers/gpu/drm/nouveau should show the offending commit fairly quickly.

Adding "nouveau.config=NvMSI=0" to the command line fixed the problem. So it looks like commit 049ffa8ab33a63b3bff672d1a0ee6a35ad253fe8 introduced it.
Any chance you might mmiotrace the blob (version 325 or later) to see which registers it fiddles with? Or alternatively, if you have a NVCE card (you never did end up providing the logs which would have made that apparent), could you try replacing nvc3_mc_oclass with nvc0_mc_oclass for the 0xce case in drivers/gpu/drm/nouveau/core/engine/device/nvc0.c? (and boot without the MSI disabling.) The switch has already been made for NVC8 in 0bae1d61c75 -- perhaps there are more "odd" ones. -ilia -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
