Same here, 10.10 was relatively freeze free for me too, the first one
happened after installing banshee and playing an mp3. I added both
options mentioned above and have suffered another full lockup (sound
stopped, mouse froze, hard reset required) in the meantime while
watching tv and typing an email in chromium on google mail.

I think I'll try disabling pulseaudio next. Any good pointers out
there to show how this is done or isn't this possible anymore with
10.10? I seem to remember a howto on how to revert to alsa.

All the best, Uwe

I can't reproduce that, what means I don't know a aplication or usage of the system making it freeze. sometimes I have uptimes of a day, without freeze and sometimes it freezes right after booting the system.

In the system log I can't find any unusual entries. But I foun that the system log is still runing, so shuting down the wifi with the notebooks hardware switch for example is logged. Also the Wifi network connection to my router is not interrupted.
