ARM450 wierd print

[gwaddle]

I have an ARM450 that threw me for a loop this morning. I have attached scans of what it was giving me. It's kind of hard to see on the scans, but if you look close at the line at the bottom of the panda chart and the top and bottom of the other test print you can see that they are not skewed, but curved. The only thing I think could cause this would be the LSU. Any other thoughts?
