I was mostly ignoring the EXT3 error on the root device and thinking that
the root device is using  SATA and the Radeon video is using PCI and the
common thing between those is the PCI bus. One is messing up the other by
some unknown conflict over the PCI Bus. You know the root device is working
with the onboard video.  This shifts attention to the plugin video card. The
combination onboard video and  and plugin video card  has caused on and off
trouble since the PC and its bios first came into existence. I was thinking
that the bios was not completely turning off the onboard video so the kernel
was loading the modules for the onboard video and they were conflicting with
the modules needed for the Radeon and the side effect was that your root
device was giving strange errors.  But I could have wandered down the wrong
path?
