congenital defect in the lvm.  you might want to schedule it
post-boot in /etc/rc.d/rc1.d.  i've nearly given up on the 
entire LVM due to the vgscan-at-startup requirement.  to 
speed things up you can use

	( /usr/sbin/vgscan && /usr/sbin/vgchange -a -y ) & 

to background the whole thing.  problem there is that you
will have problems mounting things -- can't use mount -a
to get them if lvm startup isn't in /etc/rc.d/rc.sysinit
but probably don't want anything this tricky in there at
all.  

other fix is to put the mounts directly into an lvm init.d
file and live with hard-coding them, write your own version
of /etc/fstab to mount the lvm's...  none of which are 
very pretty.
