Hi, Im a newb to working at this level with the kernel. (mainly a hardware guy) Anyways im trying to get 2.6.14 to run on my custom board. Ive got 16MB of SDRAM and 2MB of Dataflash, it enters the kernel but page faults, below is the whole nitty gritty, any suggestions on what could cause this/ were to look for a solution?
