Ok, I'll try to get a new one.

Ok, thanks.

> * How often does this happen

Sometimes its hard to work on my computer, but the fix above seems to catch
many of the hangs, I will see that the next days.   Normally its about twice a
day.

The last time it was, when I switched on HUD for unity.  I disabled this now,
since then it works fine.  The hud gave me:

Nov  9 14:28:13 martin-desktop kernel: [ 4841.054362] traps: hud-service[2006]
trap int3 ip:7f8ce47263d9 sp:7fff1d1bcde0 error:0

I don't know if this can hang a machine...

> * How can we reproduce it

That would be great if I could find that out. :)  For me I cannot see any
systematic process behind this hangs.
