I compiled a kernel by hand and then used genkernel to make an initrd because my root is on LVM. The command I used was genkernel -lvm2 initrd When I boot my system, it says /dev/vg/root is not a valid device and lets me drop into a shell to try and fix things. Before this it said that it started 0 Logical Volumes in my volume group. From the shell I try to see my logical volumes by doing: lvm lvscan It shows my 5 logical volumes, but said it can't open /dev/mapper/control. It turns out the device file is actually at /dev/device-mapper, so I made a symlink from there to /dev/mapper/control and then I was able to activate my logical volumes and boot. Could the initrc script that genkernel produces be modified to make this symlink automatically? Also, upon booting the symlinks to /dev/vg/* had disappeared, so I modified my fstab to point to /dev/mapper/vg-* instead. It'd be nice if the symlinks were in place though.
I get the same problem on x86
Can you test this patch? It edit /usr/share/genkernel/generic/initrd.scripts and should resolve the issue for you. You'll need to rebuild your initrd once you've made this change.

I just realized that I probably should have attached the patch instead. It is attached at http://bugs.gentoo.org/attachment.cgi?id=96961 for another bug. I am hoping I can kill two birds with one patch... ;]
OK. I've gone ahead and added the patch to CVS. This should fix the bug. If you find that it does not, please let us know.
I just applied the patch, rebuilt initrd, and rebooted, and everything worked like a charm! Thanks a lot for the quick response!
Fixed in 3.4.1, thanks!
Now works for me too. Well done, thanks !
