My issue is not a kernel freeze, it is clearly Xorg. I can confirm a full lockup with mouse movement, but no Xorg response. Machine is very responsive over ssh. I have killed the last application I used (firefox). - Xorg still at 100%. One CPU is 100% (2.5G) the other 1.5G.
My desktop is Xfce4.

Here are the gory details:
