Sorry, yes, to be clear, I don't get these hangs with drm-legacy-kmod. drm-kmod also "works," except when it does hang. It takes a bit of use to shake out the hang, and I'd also like to track down what's going on. I also thought to ask here, if any other Ivy Bridge users are noticing the same thing. -- Kevin Zheng kevinz5000@gmail.com | kevinz@berkeley.edu | PGP: 0xC22E1090
