Sigh. Turns out the "unwind" cleanup in ufs_mkdir() and ufs_makeinode()
has changed, but the MAC code was using the old unwinding rather than the
new 'bad' label. The EA code had an error case I forgot about, and so I
bumped into the bad unwinding code, causing the panic. Now fixed in the
trustedbsd_mac tree -- sorry for the false alarm.
