kexec on Nokia Internet Tablets

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all!

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.
