Is that as should be?
Yeah, that all looks sane. Your increased memory is because your 64GB machine had some of its memory mapped _above_ the 64GB physical memory limit that PAE has. /proc/iomem is generally just a dump of what the hardware *is*, so it shouldn't change between kernels. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
