Yes, could be caused by lvm or by specifying root (in the kernel cmdline,
through grub.conf) as UUID= or LABEL=, lvm will scan all block devices
(although it may skip floppies) for physical volumes and specifying root as
UUID= / LABEL= will cause nash to scan all block devices to find the UUID /
LABEL.
You could try working around this by specifying your root= as /dev/.... in
grub.conf
