I'm very sorry Taylor.  I was confused about the crash point and flow of 
execution of code.  scsipi_done is not re-entrant...Sorry :(

I've appended to the bug report a full dmesg, snippets of kernel error 
messages and a full backtrace on an unpactched kernel.

I hope this provides a better understanding.

The patch fixes it buy deferring scsipi_run_queue though.

Best regards,

Nat
