Jan 1 00:08:10 mcenter kernel: Unknown boot option
`md-mod.start_dirty_degraded=1': ignoring
Then how to use this param in grub?
I think we should add __setup("start_dirty_degraded=", parse_func) in
md.c, is it right?

That command line option works for me.
My only thought is that you have md compiled as a separate module rather
than compiled in to the kernel. If that is the case you need to get
modprobe or insmod to pass in the parameter I think.
