Sounds like something bad happened to your key file. Can you provide output
of following commands?

    gpg --decrypt </PATH/TO/keyfile.gpg | wc
    strings /sbin/losetup | grep multi-key-v3

First 64 KB of reiserfs plaintext should be all zeroes. Following commands
will hex dump first 64 KB of plaintext. If there are ranges of non-zero data
in the hex dump, can you provide address ranges of the non-zero areas?

    /sbin/losetup -e AES128 -K /PATH/TO/keyfile.gpg /dev/loop0 /dev/vg00/lv_crypt
    dd if=/dev/loop0 bs=64k count=1 | od -Ax -tx1 - | less
    /sbin/losetup -d /dev/loop0
