Since todays upgrade to xf86-video-intel-2.5.0-1 I've been getting "Underrun in Pipe B" errors.
The initial start of Openbox worked, but as soon as I switched to the virtual console and back, I'd only get a black screen in xorg, and the VC would be filled with hundreds of underrun error messages.
Downgrading to xf86-video-intel-2.4.2-1 fixed the problem.
A quick google showed quite a few people having the same errors.
Edit: Seems there's already a bugreport up at http://bugs.archlinux.org/task/11854

Problem appeared with 2.4.x, as you said there were many bug reports... I've tried a few patches as proposed on bugzilla, some helped but none solved the problem completly. As it happens on my machine the screen also gets garbeled, runing "xrandr -q" restores the screen, I settled on that for now (since it happens only 2-3 times a day).

Yes, well, I backported some changes from 2.5, that were supposed to help, to my 2.4.2 build... no wonder none of them solved the issue since it's still broken. If you are on arch IRC you can join #intel-gfx to get some first hand information.
