What's wrong with my kernel config ? Maybe it does not run as a 64 bit CPU ? thanks for an answer. If you want to keep your 32bit userland, you'll run into a chicken-or- the-egg-problem (because you can't run 64bit software without a 64bit kernel). To avoid this, you could get a precompiled 64bit kernel and boot with that one. Then you can use an AMD64-stage3 from Gentoo to compile your own kernel. I think, that's the easiest solution but I haven't tested it. signature.asc Description: PGP signature

Check your kernel: Processor type and features High Memory Support then select 4Gb or maybe even 64Gb if you plan to add even more later. Hope that helps.

Maybe it does not run as a 64 bit CPU ? The config for an x86_64 kernel doesn't have a high memory support option, you've built a 32bit kernel. a64bitserver linux # make menuconfig scripts/kconfig/mconf arch/x86_64/Kconfig make[1]: *** [menuconfig] Error 1 make: *** [menuconfig] Interrupt -- Mike Williams -- gentoo-user@lists.gentoo.org mailing list
