I really need some help on this one. One of our development teams is looking into ORM as a way to get code out the door faster. I've been doing a bunch of research on the topic (I'll post the links below) and I've found some interesting discussions over the pluses & minuses of the methdology. There are lots of positive examples of how well it works from all the vendors of various ORM products. I can't find any concrete examples of failed projects or long term maintenance nightmares or anything else like that. Even if ORM is the greatest thing since the flush toilet, there must be failures out there. Does anyone have any links or can provide any examples on failed or problematic ORM implementations?
I'm not trying to prevent the use of ORM, but I want as thorough an understanding of any possible problems as I can. Please help.
Here are a few of the links that I found useful:

Not really. I've been posting about it on my blog for the last two years. Our project is... well, we'll see how it turns out. At the moment, I don't have much hope for it in terms of performance or maintainability. It'll work.
