Either disable the initial bus reset in SCSI-Select or lower
the bus settle delay from 15000ms to something like 5000ms
in your kernel config. Because I enforce the bus settle
delay by blocking incoming commands from the SCSI layer, yet
the low level drivers are not responsible for timeout handling,
the top level starts timeing out probe requests with short timeouts.
The current strategy allows the system to finish inializing other
devices while the bus settle expires, but it has this vulnerability.

It is also my fault for not properly testing the default bus settle
delay. The system I tested it on had initial bus resets disabled
from a prior test of that scenario. Oops.
