6.0-RELEASE install from CD on a server with a 4TB RAID5.
This server has a 3ware 9500S-12 card with 12 400GB SATA drives in a
RAID5 configuration of approximately 4TB. sysinstall's slice editor and
partition editor both properly recognize the size as ~800 billion blocks,
however the slice editor complains about the geometry (constantly).

The label configuration requested during sysinstall was:

/ 36GB
swap 2048MB

The remainder of the slice was unused.

When sysinstall reaches the stage where it is to do the newfs, it fails
with error 36. The console on Alt-F2 states:

newfs: wtfs: 512 bytes at sector 67108863: Input/output error.

Might be related to kern/79251 but as I'm not using GEOM (unless
the installer is using GEOM) I'm filing a different bug.
Try to install FreeBSD 6.0 from CD.
At the slice editor screen choose "dangerously dedicated" (keys: F N S)
At the disklabel editor create 1 36GB / partition and 1 2048MB swap partition
Choose your install media (we use a local FTP server)
After "Last Chance" screen you'll get the error.
No fix presents itself. It appears to be impossible to install on this system.

It's been suggested that gpt can be used to partition the disk, but gpt gives "Unknown error: 0" when you try to run "gpt create". That'll go in a separate PR.
