No I have not tried the .iso yet. I am more concerned with the PCI
option i.g. I'm using Direct, if I change to MMCONFIG will it cause
this same bug?
right now I'm occupied with drinking at the moment, but tomorrow I am curious
as to see if this occurs. keep in mind if I'm going to have to deal
with having a stuck system
this means I need to use a live cd to recover the system, the problem
is SELinux why: chrooting into the hardive and then compiling is going
to kind of mess
my policy a little bit(avc's)., but anyways easily resolved within a few hours.
