Lemme see if I understand this correctly: supplying crashkernel=X@Y
influences where KASLR would put the randomized kernel. And it should be
the other way around, IMHO. crashkernel= will have to "work" with KASLR
to find a suitable range and if the reservation at Y fails, then we tell
the user to try the more relaxed variant crashkernel=M.
