I'm trying to do a 8.3-release UFS boot/ZFS root setup on an Ultra 60
(2*300 MHz, 2GB, 2*78 GB disks). I can boot into a standard FreeBSD,
OpenBSD, or Debian install, but not this ZFS install. At least not
the first time.
The first time I attempt to boot the disk, I get a "Trap 3e". If I
retry the boot from the OBP (OpenBoot 3.31) it works! I've tested on
two disks and two machines to rule out hardware.
Here's the serial output:
{0} ok boot disk
Boot device: /pci@1f,4000/scsi@3/disk@0,0 File and args:
Trap 3e
{0} ok boot disk
Boot device: /pci@1f,4000/scsi@3/disk@0,0 File and args:
>> FreeBSD/sparc64 boot block
Boot path: /pci@1f,4000/scsi@3/disk@0,0:a
Boot loader: /boot/loader
Consoles: Open Firmware console
Booting with sun4u support.

I'm manually building this UFS boot/ZFS root system from a running
standard install, with the standard install on da0 and the ZFS
install is to da1. I power down and swap the disks to test it. I
think I've rebuilt this at least 3 times now with the same trap 3e.
I dd'd the first 32kb of both disks:

Here's the recipe I used, slightly modified from
