Ok, 3.2 shouldn't have done this.  Was this an external drive?  What
else do you have on the system?

Nothing special actually. Standard arch linux with virtualbox kernel modules.
It's a SSD if this should matter. Mounted with ssd,compress=lzo,noatime.

Ok, it sounds like we've got some memory corruption problems in here.
Hopefully not from virtualbox, but I'd start with an memtest.

Is this the same FS that was corrupted or a different one?

Different one. Created from an old 3.2.1 gentoo install (btrfs 0.19-dirty).

Different FS, same machine?  Please include all the kernel messages.
