Partitioning defined in the kickstart file:

zerombr
clearpart --all --initlabel
bootloader --location=mbr --leavebootorder
reqpart
part /boot --size 1000 --fstype=ext4
part pv.01 --grow --size 10000
volgroup vg pv.01
logvol /  --grow --size=8000 --name=root --vgname=vg
logvol swap  --fstype=swap --recommended --name=swap --vgname=vg


So far I've seen this problem on one ppc64le system.
