IMHO this might be an inconsistency between devfs and your current
device files (probably non devfs based?). When devfs is compiled in 
the kernel /proc/partitions returns the devfs names.
To save scanning all block device files in /dev, lvm tries to make
use of /proc/partitions in vgscan.

Looks like a bug.
