This might be a corrupted filesystem.

Can you show ls -l /

If size is ? or permissions then its pretty clear that it is.

Anything in dmesg when you try to access any of these?

Then standard question: Which kernel?

Or try to btrfsck the fs using newest btrfs-tools. Do this with a copy of 
the device or make sure that your backup is good before.

Thats so far from a users view. A developer might have some more tricks 
for you.
