FreeBSD 5.2.1 Release:

aac0: <Adaptec SCSI RAID 2200S> mem 0xf8000000-0xfbffffff irq 16 at
device 4.0 on pci2
aac0: [MPSAFE]
aac0: i960RX 100MHz, 48MB cache memory, optional battery present
aac0: Kernel 4.0-0, Build 6008, S/N b9c0b2
aac0: Supported
Options=1f7e<CLUSTERS,WCACHE,DATA64,HOSTTIME,RAID50,WINDOW4GB,SOFTERR,NORECOND,SGMAP64,ALARM,NONDASD>
aacd0: <RAID 0/1> on aac0

There was a timeout during the initial boot process after installation at
GEOM: create disk aacd0 ... Worked out after a gentle reboot :)
