I'll try again to reproduce, but it seems to be something related to runaway swap process, (which might arise only when I hit a certain memory utilisation) and in practice appears to happen after a while of browsing, loading programs etc. rather than instantaneously whenever that particular kind of activity is run. I can get away with some browsing around, a few occasions of successful fullscreen vimeo or youtube playback, and then I get unlucky and a hang.
I usually have media playing (background audio on headphones when video isn't playing), but other than that the hosted processes are quite passive (e.g. multiple instances of evince with open documents and HTML pages with disabled flash - I disabled flash to run only on click because of this issue). Media provides an intense load on top of the existing latent memory and cpu load from other light-use programs I suppose, which might create the conditions for some kind of livelock/deadlock/race which is otherwise luckily avoided by just having more free resources. Also worth noting that I'm using powertop optimisations hard-coded in rc.local (nothing I invented myself) to maximise battery life. Hopefully these aren't related to the issue, but I can attach them if needed. I'm running the memoryx86 test now, but so far (2 hours in) there's no errors, so I guess it's not memory-related. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1220821 Title: Kernel Panic playing Youtube To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1220821/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
