Comment 3 for bug 569916

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.
