When did this start to happen? I sustect this is something similar to what has been happening with sd because of the module_init/exit stuff.
Some people are seeing lockups because of the sd changes, going back to init_module cures it. The problems is within the scsi subsystem itself.
Could you try reverting the init_sr/exit_sr to init_module/cleanup_module and removing module_init/exit please?
