 I built the world with DEBUG_FLAGS=3D-g, and installed new zfsboot and =
zfsloader on my sparc64.  However, "ctrace" isn't helpful:

>> FreeBSD/sparc64 ZFS boot block
   Boot path:   /pci@1c,600000/scsi@2/disk@1,0:a
Consoles: Open Firmware console =20
ERROR: Last Trap: Division by Zero

{1} ok ctrace
No saved state
{1} ok=20

 Anything else you can suggest to get debugging information out of =
zfsloader?
