I double checked /var/log/dpkg.log and the video driver wasn't updated.

The video is on board and I don't use it except the console when having
problems.  For example a few weeks ago I had a problem and pulled one stick
of 128MB RAM.

- You've got a CPU that isn't supported by the general -i686 optimization.


Sounds like I need to rebuild the packages or skip running a backend on this
old machine.

It's an old piece of junk AMD K6 500Mhz with one of those VIA IDE
controllers that caused all sorts of problems, but it is the best thing I
had available so I got a cheap PCI sata controller to hold a couple hard
drives.  More detailed lshw listing below.

I had attempted using it as a frontend a few months ago, but it just doesn't
have enough video or CPU.  I tried a couple old PCI video cards I have and
that didn't help enough to get it usable as a frontend.  And  I don't think
its worth the money to buy a better video card when it probably wouldn't be
a good frontend anyway.

As far as myth is concerned the machine is used for file storage via NFS and
was doing a few myth_archive jobs to move the files.  I had tried some
commercial flagging on it but it was taking way too long and decided to use
it for the archiving since it slowed the io significantly over doing it on
the master backend/frontend.    Other than that it does nightly rsync
backups of a few machines.  I don't really need to run the backend on this
old crappy 500MHz k6 but I thought that perhaps it might work better with
the new Storage Groups.

Can you post your specs on both of those items?
