Today I had the same problem, with a 2-second sound phase being looped while the rest of the system was inactive. (Yes, I have been watching a video each night for the last couple of days.) This time there were no "irqbalance Tainted" messages. I had to reboot the system by permanently pushing the off button.
I am wondering whether this is just a totem problem. It is somewhat annoying if any odd process can bring down the whole system, even if by mistake. -- totem loops in sound and blocks X session https://bugs.launchpad.net/bugs/569916 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
