Hello,
I've been doing a lot of research into a particular noise issue I seem to be having with the 5d mkII. I haven't yet found another photo exhibiting the same condition. Yes, I realize there are banding issues currently with the mkII, but the issue I'm having - I can't find similar examples. I seem to be getting not only banding, but a "linen-like" horizontal + vertical noise pattern in the shadows. Here are 100% crop examples with different lenses in different lighting conditions:

Here is the EXIF for this photo:

Are these patterns normal, or should I be concerned? Thanks very much for your analysis!

This cannot be normal! Try another card and if that doesn't help, then I would either exchange the camera or call Canon.

Are those processed pictures, or straight out of the camera?

I know that I get those patterns in shadow areas on my 30D when I try to bump the exposure up in post-processing.

They're processed in ACR, but the original RAW files were not underexposed to begin with.

The one with the bad banding problem along with the horiz/vert noise problem was shot in sraw1, the other one was shot in RAW.

That first one is ISO 100? That looks terrible, IMHO.....send it back.

Yep, the ISO100 shot looks somewhat worse than the ISO1600 shot. Hopefully, that's a typo.

if its ISO100, its pretty bad if it wasn't underexposed. Perhaps if you send me the RAW files, I can make a more valid conclusion for you? You can PM me if you want to.

Not a typo. The ISO100 one was shot on a tripod in low light, the ISO 1600 was shot in a room in a combination of available light: interior tungsten and some daylight. I no longer have the original RAW files; I have been converting them to Adobe digital negatives so I can process them in CS3, which doesn't support the 5d mkII. I don't have the space to keep both, but no matter; a test I did a week ago processing a RAW file in Canon's software and comparing it to one I converted to a .dng then processed in Photoshop produced similar results - the linen crosshatch pattern was still there. I only get this with low light conditions, but never experienced it with the XSI.
Here is a link with the .dng files:

Thanks everyone for your opinions and assistance. Merry Christmas!
