I am seeing the same behaviour with Ubuntu 14.04.3, Kernel 3.19.0-26-generic, x86_64, as soon as I mark some text in Writer and copy it to the clipboard. Sometimes, I cannot switch to the console at all, sometimes I can. In either case, I need to hard-shutdown the machine.
In all cases, I can find the the lines kernel: [ 0.0] nouveau E[ PFIFO][0000:01:00.0] still angry after 101 spins, halt kernel: [ 0.0] nouveau E[ PFIFO][0000:01:00.0] still angry after 101 spins, halt in /var/log/syslog afterwards. The problem seems to have been reported by others, too, e.g. in https://bugs.freedesktop.org/show_bug.cgi?id=87244 where a potential patch is presented. (Which, BTW, has not been back-ported to 3.19 yet.) ** Bug watch added: freedesktop.org Bugzilla #87244 https://bugs.freedesktop.org/show_bug.cgi?id=87244 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1481129 Title: System freeze when using Libre Office To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1481129/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
