Huh, this is a newly created Btrfs file system, I presume created with live-xfce. When you boot from the Btrfs install, you get a dmesg devoid of problems. When you boot from live-xfce, you get the info lock warning. Am I interpreting this correctly? I wonder if this is a problem with the initramfs, which would implicate dracut? I can't reproduce this lock message with three different Btrfs file systems of various ages, and the same kernel listed.
