The linux kernel packages for the ia64, powerpc, and sparc architectures builds device-mapper support as a module, where the packages for the other architectures have the driver built in, which leads to boot failures on ia64/powerpc/sparc when using LVM. To work around this, users must run these commands manually from the initramfs:
modprobe dm_mod
lvm vgchange -a y
This issue will be addressed in a post-release kernel update. (560717)
