I could not find wether this is constitutes a bug or some sandybridge cpus are less capable than others or different in some fundamental way. My question is: is this something that I can fix myself? And, how would I go about it? (I think it's time I get involved with my system on a deeper level.) If nothing can be done, I will just continue using the generic 64 image.
I tried installing funtoo from ubuntu and when it came time to chroot ubuntu would not recognize this command: env -i HOME=/root TERM=$TERM chroot . bash -l When I ran the previous command it echoed: env: chroot: No such file or directory And if I ran only the chroot portion of it it said something about illegal instruction and a core dumped. I thought maybe the problem was my stage tarball: intel64-sandybridge subarch, my processor is a Intel? Pentium® CPU G630 @ 2.70GHz ? 2 I think that was the right one. I'm completely lost as to what the problem is. I will try the install again with systemrescuecd, I'm worried it will be a waste of time if there is something wrong with the stage tarball.
