[arch-general] New Arch Install - Swap Won't Activate - Help the clueless?

Guys,

	I'm laughing at myself for being unable to get swap activated. Initially, when
I breezed through the install, I forgot to set /dev/sdb6 to type 82 so the box
came up with swap off (2G of ram so not much of an issue)

	But now, I want to activate it and I get an error activating swap that frankly,
I have never seen before:

[11:27 dcrgx2:~] # swapon -a
swapon: /dev/sdb6: read swap header failed: Invalid argument

Huh?

	Here are the current details of the install:

[11:26 dcrgx2:~] # cat /proc/partitions

	It looks to me like swap should activate. What am I missing? Thanks for any
insight you can lend here.
