Unexpected b_hdr change.
...We''re testing the most recent ZFS version from OpenSolaris ported to
FreeBSD. Kris (CCed) observed strange situation. In function arc_read()
he had a panic on assertion that we try to unlock a lock which is not
beeing held:
rw_enter(&pbuf->b_hdr->b_datalock, RW_READER);
err = arc_read_nolock(pio, spa, bp, done, private, priority,
flags, arc_flags, zb);
rw_exit(&pbuf->b_hdr->b_datalock); <--- THIS ONE
The only possiblity was that b_hdr for pbuf was changed somewhere. We
diagnozed this further and the b_hdr field is changed in arc_release()
function, here:

still mbuf leak in 9.0 / 9.1?
Hi list,
since we activated 10gbe on ixgbe cards + jumbo frames(9k) on 9.0 and now on 9.1 we recognize that after a random period of time, sometimes a week, sometimes only a day, the
system doesn't send any packets out. The phenomenon is that you can't login via ssh, nfs and istgt is not operative. Yet you can login on the console and execute commands.
A clean shutdown isn't possible
