It takes about 45s for the controller to respond to the IOC initialization request with a bad drive installed, but the timeout for SAS controllers is 30s. That's one way to do it. But it can fail also. In my own version of the mpt2 driver, I changed the logic and allowed for ioc port initialization to complete at a later time. Dunno what mps does (never use it). Perhaps the same thing could be done for mpt. That said, this is probably not an unreasonable change.
