Additional:

Working as "root":

        blkid

hangs (at least sometimes).

Working as underprivileged user:

        /sbin/blkid

shows many informations (and doesn't hang). But it doesn't show the  
btrfs devices/partitions.

        /sbin/blkid /dev/sdb

shows the btrfs label.

Maybe it's mostly or only a blkid problem - I'll subscribe the "util- 
linux" mailinglist.

--------------------------------

Viele Gruesse!
