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.

EIP:    0200:[<00000000>]    Not tainted VLI
