I just updated all my Beagle and Overo DSS patches to apply on the latest linux-omap head. I ran into a slight issue with parsing defaults, but saw that Tomi had already posted a workaround for that. With that patch applied I get pretty good results until I try to do something like play a DVD or display video from a webcam. At that point I get a kernel panic. See below. Has anyone else run into this?
