It was not you that I was trying to get to look at this...
but now that I have your attention :)

I did not think it pointed at cciss or the sysfs entry as
being the problem.  I was wondering more about platform probe
timing, the bios, and how each card firmware reacts given
what I thought the patch did.  I could be totally wrong about
that as I work at the filesystem level.

We have not seen the problem yet but we have different
proliants/smartarrays.

If you can try it on matching hardware, great, if not
then someone will eventually find a system to test it.
