I have a SRCU42X in a server with Intel motherboard (SE7501HG2), and have not made it crash yet. However, the box is not in production yet, so... I ran more generic tests and did not apply severe pressure on the disk subsystem: endless loop of buildworld -j8 bonnie++ running with one instance per array I think it ran for a week or so without any issues. But I would really like to try whatever you did to your servers to find out if I'll have the same issues here :-) -- Frode > Could this indicate a bug in the driver, or at least in its support > for our re-badged RAID controller?
