I just tried -rc5. Now suspend to disk seems to work. I think the XFS 
workqueue patch fixed this.

It can also suspend to RAM, but resume is worse. The first time around it 
resumed but corrupted the vesafb console (greenish blinking character cells), 
something that used to work before. But the system responded to input, so I 
suspended to RAM again. This time the resume failed, it hung after 
printing "Linux!" in yellow at the top of the screen. (Seems to be some 
artifact, I have seen it before even with working suspend.)

I'm attaching my config.

Not sure how to bisect this. I guess it would be necessary to keep the XFS 
workqueue patch throughout, otherwise it is guaranteed to break.
