I had the same problem with a RR1740x controller with that kernel. I
was able to successfully compile the driver when I upgraded the kernel
to 2.6.22.... being sure to get the correct syms. Since then, I've
been able to run the controller just fine. My problems started with
>2.6.18.... until .22+ It is continuing to work with .17 and .25 in
the alpha 11 of SuSE. It is a pita, to be sure, but I am no happily
running a 2.5TB raid5 with that controller under SuSE 10.3.
As to conversion: I suspect that it is a real PITA to try. The
formats are entirely different and you have to have a small boot
partition in order to load the drivers for the software raid. I tried
and gave up on that idea, at least until RR decides to actually support
their controllers under Linux the way they do for Microsloth.
I suspect the 172x controller will play out the same way as the 174x
controller did as I believe they use the same chipset, the main
difference being how they handle the physical interface, eg, number of
Once I got the RR1740x to compile under Linux with a less buggy kernel,
I have had zero problems with the card other than lack of any real
support, though the driver source did not need modifications once the
kernel issues were resolved.
