I have this problem too.It may be related to vdpau,as flash 10.2 can make use of it,and can cause this happen quite predictably(possibly mplayer with vdpau or vaapi-vdpau driver can as well,not sure though).Were You running any apps that use vdpau(including flash 10.2)?also if nouveau is available maybe use that instead of nv(Im not on ubuntu so I'm not sure its there,but I believe so.)nv is being phased out if I'm not mistaken,and nouveau may run smoother as well.
