You can try to explicitly specify the RAID to the kernel instead of relying on autodetection. Add the following line to your kernel parameter list: raid=noautodetect md=3,/dev/sda1,/dev/sdb1 root=/dev/md3 the first parameter on md= is the number of the md node. So if you want it as /dev/md3, you specify the 3. The RAID level is automatically detected. Other then that: Make sure the mdm subsystem is really compiled into the kernel and not a module. Hope this helps, Florian Philipp
