Exactly. The bios sees the drives and can start the boot process
by loading the NetBSD bootloader from either one of them and that
bootloader can read "/netbsd' from either one of them and get that
running but then one or both of the drives then disappear *sometimes*
so the raid array is not available, or only one of the drives is
available.

I have no idea what is going on. What was in the dmesg above is
the only clue I have seen that might explain why wd2 and wd3 aren't
being seen by the kernel *sometimes*. When they both are seen the
WDCTL_RST failed messages are not in the dmesg and this is all
there is instead:
[ 2.158118] ahcisata1 port 0: device present, speed: 3.0Gb/s
[ 2.158118] ahcisata1 port 5: device present, speed: 3.0Gb/s
[ 2.158118] ahcisata1 port 4: device present, speed: 3.0Gb/s
