I have this problem constantly. I agree this seems to be triggered most often by pulseaudio. I'm using an epa kernel mod for Oneiric which sets a nice value of -12 for pulse (I've used it since. The most common way to trigger the crash is when an internet ad on a website like yahoo tries to push audio through firefox while I'm listening to music with any music player. Firefox works fine but pa sometimes stutters in threadbuffering and the desktop crashes behind firefox (memlock?) and icons and sometimes even characters become corrupted. It seems there is a ruthless thread in buffer overrun. Also happens frequently when a second user logs in to the same Ubuntu box. Perhaps there's a bug in thread cloning between pa and gvfs? Bad header info in the XXXThread.clone of one or both? I'm not a thread expert but these are issues worthy of someone more familiar with the specific projects I suppose.

From what I have determined, it is caused by thread locking, and gvfs- fuse-daemon. The way to make it happen seems to be to use my computer for a while, and then sooner or later, a program freezes. When it does, if I open system monitor, it will show the waiting signal for the frozen program to be futex_wait, and will show the waiting signal for gvfs-fuse- daemon to be futex_wait. I've tried to find information about futexes, but the web is pretty quiet on the matter. This bug seems similar to bug 303190, but I think it's different. The only solution I have found to this bug is to kill the application that is frozen. This has happened to: - gnome-panel - gnome-do - firefox - eclipse - python - getty (I think) - and a few others Every now and then my computer freezes, and I think this is the culprit because if this happened to a process like gdm, it would cause me to be unable to figure out the waiting channel. Also, I'm not sure if this helps, but I installed with the encrypted drive option via the alternate installer. If there is anything I can do to provide a less subjective bug report, I'd love to help, but I've little idea where to go from here so this can be confirmed. I've attached a screenshot of system-monitor at the time of the current futex_wait lock-up.
