I'm having this same problem. I downloaded CF-Auto-Root-v1awifi-v1awifixx-smp900.zip from download.chainfire.eu. I extracted the zip file, leaving me with a tar.md5 file. I try to flash that file, and end up with multicolor bars across the screen, exactly like if the video card dies on a mobile.
Here's what Odin has output as of when the error occurs. It flashes up a big red failed in the upper left box.
<OSM> Enter CS for MD5..
<OSM> Check MD5.. Do not unplug the cable..
<OSM> Please wait..
<OSM> CF-Auto-Root-v1awifi-v1awifixx-smp900.tar.md5 is valid.

So I flashed the original recovery from http://forum.xda-developers.com/show...&postcount=234
and got a working but unrooted tablet. And I flashed CF with both 3.09 and 3.07, with a flash back to stock before each. Same thing every time-picture of a dying video card, except display is fine once flashed back to stock. Pic of the display added, on the off chance it helps.
