I want to make kexec work on current Nokia Internet Tablets but maybe someone here have a clue or better if a patch :) When I run a kexec enabled linux-omap kernel and try to boot the production Maemo kernel or a linux-omap kernel I only succeed if the serial-console flag in r&d mode is set, if not the device just hangs. It seems as a timing problem because if I insert small delays to the kexeced kernel via CONFIG_BOOT_PRINTK_DELAY it works too without the serial-console flag set. Any idea what to debug or where to start? Thanks. -otto
