Well, it's a bug in the CPU. If the LCDC DMA is running, the cpu won't reboot with a simple "mov pc, r0".
Ummm... you don't call this a "reset", do you?
And how about the AT91RM9200(DK) where the author wants to "shutdown the console to avoid strange chars during reset"???
Well, that's IMHO polishing, and forgiveable ;-)
In your case, I think you really want to implement a _real_ reset function that takes the CPU back into it's virgin state. Is there a watchdog on this hardware?
