One thing that stood out for me is the check `expose_physicals > 0` instead of `expose_physicals != 0`. But that commit exists since 2.6.35 ... This very much looks like an upstream kernel issue and therefor it's better to bring it to the attention of those maintainers. Those are: $ scripts/get_maintainer.pl drivers/scsi/aacraid/aachba.c Adaptec OEM Raid Solutions <aacraid@microsemi.com> (supporter:AACRAID SCSI RAID DRIVER) "James E.J. Bottomley" <jejb@linux.ibm.com> (maintainer:SCSI SUBSYSTEM) "Martin K.
