I'm using a serial console, not video, maybe that's related somehow. Yep, that's what it is... I dug out a monitor and hooked it up, and that gives me the same symptoms you're seeing. The problem is, I have no idea what to do about that. Those register dumps are printed by uboot's exception handlers, and this happens while the efi loader is loading the kernel. I don't know much about efi or about running arm systems with video monitors connected. -- Ian
