Seems to be 
bob@www:~ % sysctl kern.cam | grep delay
kern.cam.scsi_delay: 5000
kern.cam.debug_delay: 0
kern.cam.boot_delay: 20000

Didn't change when I plugged in the adapter. Incidentally, the
machine didn't panic when I unplugged the adapter this time. 

Serial console output returned to normal after unplugging with

The login prompt returned as usual.
