Bug Description
Binary package hint: pulseaudio
Description:
While playing a media file (video/audio) with any player (totem, rhythmbox, vlc, ...) playback halt for a while, everything becomes slow as though a process has spawn in background, locking all the system resources. Then i hear the sound of the hard-disk spinning as though being busy with some I/O operations. Ultimately the system freezes and the only remedy is a manual reboot. If I hit Ctrl+Alt+BkSpace at the onset of this issue I get some chances of rebooting X to the login screen.
How to reproduce:
*Login into natty
*Enable pulseaudio (if not enabled/installed)
*Open a player, e.g. vlc, and reproduce some audio/video
*Wait for a while untill playback halt for a few seconds. Then the os becomes unusable.
A possible solution:
*"autospawn=no" pulseaudio
*kill the daemon (pulseaudio -k)
Further remarks:
The solution outlined above is what led me to conclude that the problem is related to pulseaudio. There are some chances that this is an hardware-related bug, for it seems that this isn't a common bug (also see https:/

Maybe this bug is not so hardware-dependend as i originally thought. The same issued presented itself on a completely different machine. I presume that I'm not the only one with this bug, and that it'd been already reported under different tags.
