I run F20 root FS with F21 **3.12.1-2.fc21.armv7hl **kernel. (see http://www.swissdutch.ch:4999/ ) on my Wandboard quad.
I cannot boot from sata, as the root FS is being mounted about 4 seconds before the sata device is ready during the fedora boot process. (And yes, I understand uSD card is needed for uboot, kernel, mouting /boot fs etc. That is perfectly acceptable - I just want the root FS and swap to be coming from Sata for obvious reasons).
I try to understand the magics of Fedora boot, initramfs and the likes. It seems I need to get a PhD for this! ;-)
*Question*: how do I ensure the root fs is mounted /AFTER /the sata device is ready??? Some people suggested adding a sleep command ro a dependency - my question is where and how in the initramfs do I do such a thing???
(again, when booting pointing the root fs to the sd card, the sata is working fine at the first login as seen with fdisk -l).
Cheers, Ronald

does rootwait=10 help or is that a debian thing?

Unlikely, I don't have one ;-)

dracut controls the initrd and the entire early boot process. Most things you should be able to add to /etc/dracut.conf and then you'll need to regenerate the initrd using dracut. The man pages and docs are relatively good.

It sounds like your not getting the right modules into the initrd. Make sure you add the appropriate modules into the dracut.conf and then regenerating the initrd.

Apologies I meant rootdelay=<seconds> (I use this on a machine with a rather slow CF card as a rootfs)
