Sorry for the ambiguity, what I mean is that booting from the previous
kernel loads all cards just fine, even the one that "failed to open" in the
newer kernel.
I have successfully changed boot order with other systems, but in this case
the working kernel is in a sub menu, I have to select "advanced" then the
previous kernel, how would that work? Can I add two numerical values into
the boot order?
