Hi karsten

Would you mind updating to the latest mesa git as there is a patch[1] that
resolves segfaults with nouveau_vieux_dri

On top of that note that bugs in the nouveau-dri mesa driver
(/usr/lib64/dri/nouveau_vieux_dri.so), are not covered [2]

If you boot the system with "nouveau.noaccel=1" and X still segfaults,
please
attach both dmesg and Xorg.log of that session

Please give us a shout if the patch/latest git worked or not.


Thanks

Hi Emil,

mesa git doesn't change anything...

Don't know what mesa actually has to do with this bug, because backtrace in
Xorg.0.log shows only involvement of xorg-server and xf86-video-nouveau.
Can't see mesa in there, therefore I posted this bug here for nouveau
driver.

Tried mesa git unsuccessfully with and without acceleration.

But got now additionally:
glxgears used greatest stack depth: 3376 bytes left
in dmesg.

After discussion over #nouveau it turns out the issue was caused by nouveau-dri

By removing nouveau_vieux_dri.so the problem has been resolved

Marking as resolved:invalid due to bug policy
