 I devised a procedure to test -current on the fileserver without risking
 the RAID if disks fail to be detected--reboot in single-user mode,
 disable autoconfiguration and boot the test kernel in single-user mode.
 
 Booting a 9.99.17 kernel (the first I've built since the switch to GCC-8)
 seems to detect wd0 (the first in the RAID set), but still complains
 about IDENTIFY FAILED and can't find identify wd1-wd3 (more RAID disks)
 at all.  These are all on the siisata card.  The system disk is wd4 on
 the onboard piixide parallel bus and wd5-wd8 (the rest of the RAID) are
 on the onboard Intel ahcisata ports.
 
 I captured the dmesg before rebooting with its normal system (8.1_STABLE).
