dracut error netbooting Power7

[Bryson Lee]

Hi,

I'm trying to do a network-based install of Fedora 16 on an IBM PS710 (8231-E2B).  I have existing Cobbler infrastructure that we're using to provision these boxes with Fedora 12, so I'd hoped to be able to give F16 a quick spin to see if we can start thinking about moving forward.

The DVD iso appeared to import cleanly as a Cobbler distro, and the box successfully TFTP's yaboot, vmlinux, and the initrd and _starts_ to boot the kernel, but Dracut issues a " FATAL: No or empty root= argument" and then panics the kernel.  I've included the message output below.

Any suggestions?  The only place I can think of to put a root= argument is in the Cobbler-generated yaboot config file, but I don't know what to specify there...

Thanks,

-Bryson
