The issue is very likely in the driver, not the firmware.  I'm just
trying to figure out whether it broke in LSI's Phase 16 or in our
additional changes in FreeBSD.

In any case, I've reproduced the problem, and hopefully I'll know soon
where the issue is.

So don't worry about trying LSI's driver.  Just go back to the previous
version of stable/9 that worked for you until we fix it.

This only affects RAID volumes, not regular disks.
