One last data point about the VPN1411 (Hifn 7955) in the Net4501:  If I
run with "pseudo-device crypto" but no FAST_IPSEC, I can trigger what
seems to be the same bug with a simple benchmark:

time dd if=/dev/zero bs=1m count=100 | openssl aes-128-cbc -out /dev/null
This hangs after one output block from dd, and I get:

        hifn0: abort, resetting.
        hifn0: proc unit did not reset

in the message buffer.  Sometimes I get

	hifn0: overrun ffffffff

first (I saw it when testing with des-ede3-cbc, which also fails) and
sometimes I just get the "abort" message first.
