But in the success case, the initrd is located _before_ the node 0 region: [ 0.000000] Initmem setup node 0 [mem 0x0000000008000000-0x000000000fffffff] [ 0.000000] initrd: 0783283d - 08000000 -- Andreas Schwab, sch...@linux-m68k.org GPG Key fingerprint = 7578 EB47 D4E5 4D69 2510 2552 DF73 E780 A9DA AEC1 "And now for something completely different."
