whenever i try to boot my gentoo-2.6.28-r1 kernel, i get an error spamming the console. i forget the exact terminology, but i believe it's: "FATAL: modules: /sys not mounted" it works fine when i roll back to gentoo-2.6.28 and i can even use the gentoo-2.6.28-r1 initramfs. if i try to use the kernel of that version, however, i get that above-mentioned error and it spits me into my initramfs' busybox. -i am using genkernel (ver. 3.4.10.903) -i have already tried rebuilding the kernel via genkernel but no luck -i was previously able to boot this kernel up until today -i ran an emerge -uDNv world yesterday, i think this issue may possibly be tied to my (re-?)emerging sys-apps/module-init-tools-3.6 OR i just noticed this: https://bugzilla.redhat.com/show_bug.cgi?id=484552 it seems tied to a libnuma but i have no idea what ebuild that would fall under in gentoo's portage.

just some updated info- the message spammed is actually "modprobe: FATAL: /sys is not mounted" this is bugging the crap out of me.
Could we have the .config of your 2.6.28-r1 kernel and the config of your 2.6.28 kernel? Also, please don't change the severity field of the bug. It would be a waste of panic in case this is not actually a bug. Rest assured that we pay attention to every bug that appears in here :)
ah! terribly sorry- i noticed it was changed after i updated it. i thought i had originally marked it critical and then thought i was mistaken.. guess i wasn't. :) i'll include the .configs for both as .gz and a plaintext diff of the two for ease of comparison in just a second

Created attachment 181498 [details] .config for 2.6.28
Created attachment 181499 [details] plaintext config for 2.6.28
Created attachment 181500 [details] plaintext config for 2.6.28-r1

Alright, the "modprobe: FATAL: /sys is not mounted" is definitely a product of module-init-tools-3.6's (3.5 didn't contain that check) modprobe, which checks to see if /sys/module exists in handle_module(). What confuses me, is that initramfs uses an insmod wrapper called modprobe, instead of the normal userspace modprobe coming from module-init-tools. That initramfs modprobe contains no checks/FATAL errors regarding sysfs whatsoever. We also see that in genkernel-3.4.10.903's defaults/linuxrc mount_sysfs happens before any modprobing takes place. So, for a reason I don't quite grasp yet, the modprobe tool from module-init-tools-3.6 tries to check if /sys/module exists, fails and *spits you back to your initramfs' busybox*. Which is even more mysterious, since that means that the rootfs that initramfs was on, did not get overmounted, init was called and somehow you got threw back to initramfs which shouldn't had been there at that time. And beyond all that, it's also a 2.6.28-r1 regression (?!). Could you, please, check again if 2.6.28 will boot alright with the same module-init-tools and genkernel versions as with 2.6.28-r1? (There is also a high chance that all the above are actually BS. I'm gonna take another look, tomorrow, to see how all the above can be linked together to produce a fix (or a sci-fi book))

Would you be kind enough to try the latest stable vanilla kernel (2.6.28.4) off kernel.org? If the bug appears in the vanilla kernel too, I'm gonna ask you to use git bisect between 2.6.28 and 2.6.28.1 to find out which commit introduced the bug. But let's see if the issue is fixed in the latest kernel releases, first.
