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

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

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

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