I'm not sure of the criteria, but this is what I'm running:

I added ahci_load="YES" to loader.conf and rebooted. Now I see:
You can add siis_load="YES" to loader.conf for SiI 3124.
Ahh, thank you.
I'm afraid to do that now, before I label my ZFS drives for fear
that the ZFS array will be messed up. But I do plan to do that for
the system after my plan is implemented. Thank you. :)
They won't be messed up. ZFS will figure out, using its metadata, which
drive is part of what pool despite the device name changing.
I now have:
siis0: <SiI3124 SATA controller> port 0xdc00-0xdc0f mem
0xfbeffc00-0xfbeffc7f,0xfbef0000-0xfbef7fff irq 17 at device 4.0 on pci7
siis1: <SiI3124 SATA controller> port 0xac00-0xac0f mem
0xfbbffc00-0xfbbffc7f,0xfbbf0000-0xfbbf7fff irq 19 at device 4.0 on pci3
And my zpool is now:
$ zpool status
pool: storage
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
storage ONLINE 0 0 0
raidz1 ONLINE 0 0 0
ada0 ONLINE 0 0 0
ada1 ONLINE 0 0 0
ada2 ONLINE 0 0 0
ada3 ONLINE 0 0 0
ada4 ONLINE 0 0 0
Whereas previously, it was ad devices (see
http://docs.freebsd.org/cgi/getmsg.cgi?fetch=399538+0+current/freebsd-stable).
Thank you (and to Andrey V. Elsukov who posted the same suggestion at
the same time you did). I appreciate it.
> I don't
use glabel or GPT so I can't comment on whether or not those work
reliably in this situation (I imagine they would, but I keep seeing
problem reports on the lists when people have them in use.......)
Really? The whole basis of the action plan I'm highlighting in this
post is to avoid ZFS-related problems when devices get renumbered and
ZFS is using device names (e.g. /dev/ad0> instead of labels (e.g.
gpt/disk00).
