The Debug File you attached indicated the freeze happened during scan of the LSI adapter, but such this kind of issues can sometimes no provide accurate indication where it happened, because when a storage driver freezes, the debug file might sometimes not be completely written. Did you have the "Debug Write Direct" option enabled ?
I have also noticed the rather unusual "bxois" storage driver, which should belong to the Broadcom adapter and also thought this might be the reason. Can you attach another debug file when the Broadcom adapter is disabled ?
