*Something* looks to the kernel like a SCSI interface else this 
wouldn't happen.

"sysctl kern.cam.scsi_delay=100" isn't going to do any good because its 
applied after the kernel has loaded and the SCSI delay is long past. 
Maybe it would work (without the "sysctl" prefix) if placed in 
/boot/loader.conf but the foolproof brute force fix is to create a new 
kernel configuration and change this line, then build/install a new 
kernel. (example out of GENERIC):

options    SCSI_DELAY=15000    #Delay (in ms) before probing SCSI

If one is really sweating for "maximum performance" then one would 
already be building custom kernels stripped of the devices one does not 
have.
