I'm running Gentoo Linux with a custom compiled kernel and I've just migrated from a 2.6 kernel to a 3.5.

As my HD's are on RAID 0 mode I use a custom initrd file in order to be able to boot. While kernel 2.6 is able to boot without problems the new 3.5 compiled kernel fails to boot complaining about no block devices found. After taking a look at initrd.cpio contained scripts I can see the failure message is given by mdadm tool.

Does anyone has a clue about that?

Edit: this morning i noticed there was some kind of issue on my old initrd which works fine for 2.6 kernels, so created a new initrd which works fine and let me to boot into GNU/Gentoo Linux with same 3.5 bzImage.

It could be an issue of mdadm, gonna check it.
