panic: ffs_vfree: freeing free inode

[Rumko <rumcic@xxxxxxxxx>]

As far as I know, it happened while another partition was being fsck-ed, but
other than that, there shouldn't have been much activity on the machine at the
time.

Unread portion of the kernel message buffer:
dev = #ad/0x20045, ino = 15, fs = /home
