6.0-RELEASE on a server with a 4TB RAID5.
>Description:
This server has a 3ware 9500S-12 card with 12 400GB SATA drives in a
RAID5 configuration of approximately 4TB. When you run "gpt create /dev/da0" it gives the error:

"gpt create: error: bogus map"
"gpt create: unable to open device `/dev/da0': Unknown error: 0"

No combination of gpt flags appears to let you get past this.
>How-To-Repeat:
Run "gpt create /dev/da0" on a system with a >2TB RAID (4TB in this case).
>Fix:
Unknown.
