Looks like your config ends up waiting for root on the mmc. But we're missing what was board-n800-mmc.c, so that needs to be updated for mainline. You can find the old code in the omap-2.6.30 branch under arch/arm/mach-omap2 if you have the cycles to update it. Also, the drivers/cbus needs to be updated to get the GPIO pins from board-*.c files, otherwise the retu watchdog will power down the system in 30 seconds. > I am using the arm-linux-gnueabi cross-compiler from emdebian, v4.2.

I've tried it both ways... Yeah, that's needed only for the serial console. Regards, Tony
