I also had a lot of problem to get a btrfs-aware initramfs working properly.
One of the biggest proble was to find the right list of modules. Btrfs depends
by crc32c, and I need a lot of retries to discover it.
The main problem was that if the module is not available (it is the case of a
initramfs) btrfs doesn''t start...
When you say " it just trying to mount every device in the array in
turn", do
you mean in the initarmfs ?
