Ok, I'm particularly suspicious of one patch, ptrace_ldt-reload-smp-fix, try
unapplying that one. I don't know exactly *how* it might trigger that crash,
but it seems a data corruption, and that code is doing exactly that.
In addition, below, the segment selector is totally fucked up. It is a ring 0
GDT segment, which is however non existant. It would exist only if there were
a third CPU, and would be a NULL descriptor anyway.
