The originally reported "[TTM] Failed to expire sync object before buffer eviction" smell like a kernel issue too, and probably one that's fixed in upstream kernel. They don't show up when I boot into today's kernel.org's 3.11.0-rc7 (commit a8787645e14ce), and are probably fixed by recent drm/noveau changes since 3.11.0-rc6
My original issue seems to have gone away when I realised that box was using lightdm, not gdm, and lightdm is no longer supported. If I see problems when reverting to ubuntu standard kernel, while keeping gdb, I'll re-raise against kernel. So this is just Fabio's issue -- apologies for conflating the two when "failed to expire sync" seen -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1208207 Title: driver crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1208207/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
