Since I added tunables a while back, it should be safe to remove the setting from GENERIC entierly, at least in CURRENT. The default is 2 seconds and works fine for most applications. You can always set kern.cam.scsi_delay to a different value in the loader if you have devices that need more time. -- Brooks -- Any statement of the form "X is the one, true Y" is FALSE.
