This is similar for the Bay networks/Xylogics Micro Annex ELS, Annex 2000,
and 4000 series and probably a lot more.

Running proff's 'strobe' on a bay/xylogics annex will result in instant
hanging of the annex, leave it go for 30 seconds, then come back to the
annex and you'll see load averages near the 100% mark.

For the duration of the strobe the device is rendered unusable.

You don't really have to do anything quite that sophisticated.  All you
have to do is make multiple connects to listening ports on them quickly.
Some sort of race condition.  If the port scanner you're using is remotely
efficient, up it goes.  I'm not surprised that they are vulnerable to more
complex attacks if their base IP stack can't even handle rapid-fire SYN
packets on different ports.
