--- Comment #1 from Chris Wilson <chris at chris-wilson.co.uk> ---
If I know which bug you are talking about, it is not actually a bug in the DDX
or even X. But the kernel hangs when X tries to VT switch. If you do have ssh,
you could grab the log (so I presume you don't!) and could even attach gdb to
verify where the hang occurs.

This prevents the kernel bug from causing X to hang:
