I can't boot a GPT partitioned 5.5 TB disc, where the UFS root partition
is near the end of the disk. If I put another disk in the system and
mount root from the GPT disk the system runs fine.
The 5.5 TB disk is partitioned:
bigback# gpart show

If I try to boot it (disk1 so pressing F5 here) it fails looking like
this (there is no UART available so this is typed from a pic, with typos):
F1 FreeBSD
F5 Drive 1
Default: F1
BTX Loader 1.00 BTX version is 1.02

can't load 'kernel'
Type '?' for a list of commands, 'help' for more details
OK
To get this far suggests to me that PMBR and GPTBOOT worked, and that
the problem is elsewhere. Suggestions? Could there be a 32-bit
truncation lurking in a loader somewhere?
PS. Note that the "lsdev' command causes the loader to crash while
printing out the info on the big disk, right after the EFI line for ad6p1...
