Kernel Config:
--------------
[*] Multiple devices driver support (RAID and LVM)
<M> RAID support
<M> RAID-0 (striping) mode

- everything else from that submenu disabled!

/etc/raidtab:
-------------
raiddev /dev/md0
       raid-level 0
       nr-raid-disks 2
       nr-spare-disks 0
       chunk-size 4
       persistent-superblock 1
       device /dev/hde2
       raid-disk 0
       device /dev/hdf2
       raid-disk 1

hde2 and hdf2 are type fd. Made with mkraid /dev/md0.

mkraid /dev/md0 hangs with the mentioned patch some time ago.
RAID detection hangs at boot with the mentioned patch ... bla ^ ;)

w/o all works. Anything else you need?

ciao, Marc
