I have a megaraid 428 (oem'ed by Dell in the PowerEdge 6300) configured
with 3 logical units (each 2 disk RAID-0). There are also three other SCSI
controllers on the motherboard.
In Linux-2.2.2-ac1 or earlier, all three devices showed up.
In later versions (up to 2.2.4-ac1), only the first unit shows up. Mount
attempts to the second and third unit give "no such device" errors, and
halt the boot sequence.
How can I make all 3 devices show up again?

Here is how it boot in 2.2.4-ac1:
