Something is not right in the IO space. The messages talk about
vendor ID = 11AB
0x11AB Marvell Semiconductor
TMC Research
Vendor Id: 0x1030
Short Name: TMC
Does "fmdump -eV" give any clue when the box comes back up?

I'm attaching a screenshot of the console just before reboot. The
dump doesn't seem to be working, or savecore isn't working.

I'm working on testing this some more by doing a savecore -L right
after I start the copy.
BTW, I'm copying to a raidz2 of only 5 disks, not 16 (the chassis
supports 16, but isn't fully populated).
So far as I know, there is no spinup happening - these are not RAID
controllers, just dumb SATA JBOD controllers, so I don't think they
control drive spin in any particular way. Correct me if I'm wrong, of
course.

The copy operation will make all the disks start seeking at the same time and
will make your CPU activity jump to a significant percentage to compute the
ZFS checksum and RAIDZ parity. I think you could be overloading your PSU
because of the sudden increase in power consumption...
However if you are *not* using SATA staggered spin-up, then the above theory
is unlikely because spinning up consumes much more power than when seeking.
So, in a sense, a successful boot proves your PSU is powerful enough.
Trying reproducing the problem by copying data on a smaller number of disks.
You tried 2 and 16. Try 8.
