Hi Heinz,
Seeing as all the major distro's use this for detecting RAID during install from live CD, and right now they all fail, then you might suggest to them that this project is dead and you no longer support. Quite why they started using this for RAID, I am not sure. It did work, then got broken. Maybe they still think it works? It does not.
Please ask the major distro's to start using mdadm instead of this broken thing they are still using.
Regards
David

Have you tried mdadm? isw should be driven via md by now.

Subject: Rebuilding a Raid 1
Date: Thu, 25 Apr 2013 06:52:01 +0200
I'm trying to rebuild a raid 1 (dmraid+isw) unsuccessfully. I replaced the failed disk with a new one and the BIOS added it automatically to the raid. Running kernel 2.6.18-194.17.4.el5.
# dmraid -r
/dev/sda: isw, "isw_babcjifefe", GROUP, ok, 1953525165 sectors, data@ 0
/dev/sdb: isw, "isw_babcjifefe", GROUP, ok, 1953525165 sectors, data@ 0
# dmraid -s
When i try to start the raid i receive the next errors*** Group superset isw_babcjifefe --> Subset name : isw_babcjifefe_Raid0 size : 1953519616 stride : 128 type : mirror status : nosync subsets: 0 devs : 2 spares : 0
