I think I'm seeing this too. I get at least one X crash (forced logout) or kernel crash (hang, flashing keyboard lights) every day.
This is in 12.04. When I installed (fresh install) that was linux- headers-3.2.0-20; still happening now in -23. I'll attach files showing relevant segments of syslog (for X crashes) and kern.log (for kernel crashes). ** Attachment added: "section of kern.log relating to X crash" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/978342/+attachment/3077667/+files/nv_kernel_error.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/978342 Title: Kernel panic on 3.2.0-22-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/978342/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
