	root (nd)
	kernel /rhel6.0/vmlinuz ip=dhcp method=nfs:192.168.16.1:/var/ftp/rhel6.0x64/
	initrd /rhel6.0/initrd.img

title Red Hat Enterprise Linux 6.1
	root (nd)
	kernel /rhel6.1/vmlinuz ip=dhcp method=nfs:192.168.16.1:/var/ftp/rhel6.1x64/

This can't be fully evaluated until the traceback that results is attached to the bug, but it's certainlty not an efibootmgr bug.  Reassigning to kernel, though it could still be a grub problem or a dhcpd.conf configuration problem.  No way to tell until we see the traceback.

Comment 4 Matthew Garrett 2011-12-13 13:34:06 UTC

For some reason the kernel's being asked to boot from /dev/ram0. Reassigning to anaconda.

Comment 5 David Cantrell 2012-01-03 20:34:13 UTC

This can't be an anaconda problem yet, anaconda isn't running.  Too vague.
