[SOLVED] can boot fallback kernel but not normal (macbook pro 7.1)

Hi!

I installed arch on a macbook pro 7.1. I'm using grub2. (using an ext2 partition with the bios_grub flag on)

I can boot the fallback kernel succesfully, but, when I select the normal boot option in grub, I get

Root device /dev/disk/by_uuid/<long string here> doesn't exist.
Unable to determine major/minor number of root device "/dev/disk/by_uuid/<again that long string>".

Then I'm dropped to the recovery shell.


Does anyone know what could possibly generate this kind of error?

I just tried something that might shed some light on what's going on. I edited the normal kernel entry for grub to use kernel26-fallback.img instead of kernel26.img, and booted succesfully, so it seems is purely a kernel issue. (something missing from the regular kernel?)

any ideas? sad

This might help :
# mkinitcpio -p kernel26

indeed! BUT, I had to remove the autodetect HOOK from mkinitcpio.conf. 

Now it works as a charm.

Thanks a lot!
