Hi!
I detected a problem with an Intel (imsm, ICH) RAID1 reported as "clean" by Linux, while the BIOS and Windows claimed the RAID is in state "rebuild". This was for an older kernel, and the bug had been reported to openSUSE bugzilla as bug #902000. Anyone interested can find the details there. I thought the problem is important enough to let you know...
Regards,
Ulrich
