In case someone else has stability issues with OI using an LSI 9240-4i controller with the imr_sas drivers (version 3.03) in the future. I have traced my stability issues to the controller. Reflashing the controller to IT mode (following instructions at http://www.servethehome.com/ibm-serveraid-m1015-part-4/) which then uses the builtin mpt_sas drivers seems to have cured the spontaneous server reboots.
