SubjectRe: general protection fault: 0000 [#1] SMP
<---- cut -------->

cleaned the thread up.. Anyways after doing some debugging with gdb and
with valgrind for an application that keeps segfaulting I noticed this
in dmesg:

from what I remember using valgirnd with the app took a while to load
but am unsure if is the reason for the above message.
