Looks like a firmware bug - do you have the latest firmware? Drive
firmwares? Anything in the drive error logs (using smartctl)?
If not, then try opening a bug on the kernel bugzilla - LSI engineers
read that (and sometimes even fix things).
Otherwise, you could try replacing with a straight SATA contoller, if
that box doesn't have a SAS backplane - I've not been to impressed by
the quality of engineering for LSI contollers, and SATA-on-SAS in
general hasn't been very reliable IMO. Just go for a well supported
SATA controller (e.g. Sil 3132 etc.).
