i wanted to let you know that i tested your advice. And let me say, it's was a 
damn good advice :) I can boot FreeBSD loader on Linux 3.8 now, no SHA256 
checksum failures. And no panics with FreeBSD LiveCD anymore too.

I just inserted hard_irq_disable() after each local_irq_disable() in 
arch/powerpc/kernel/machine_kexec_64.c

Awesome ! :-)

Care to send a patch with a Signed-off-by: ?

Cheers,
Ben.
