After working with many FreeBSD boxes, mostly Dells and a few IBM servers, they can take forever (2 to 3 minutes) which seems like forever when one is trying to get back on line quickly. If one is using a serial console, the \|/-\|/- of the kernel loading doesn't start until most of that time is gone. I am guessing the actual FreeBSD kernel bootup is maybe 30 seconds or so. If you have a SCSI bus, be sure the settling time built in to the boot process is as short as will still work correctly. Earlier versions of FreeBSD waited 15 seconds default. I safely got it down to 1.5 seconds and might have even gotten it shorter if I really knew how long it took the bus to settle.
