em0 with latest driver hangs again and again (without "Watchdog timeout" message!)

[Mike Tancsa]

I have been running with 7.2.2 and so far so good.  However, its hard to
say in my case as the box I would only periodically see the issue.

Jan, have you had a chance to try 7.2.2 ?  You seemed to hit the issue
the most frequently. There are also some alternate patches in

http://www.freebsd.org/cgi/query-pr.cgi?pr=150516

But I think Jack said 7.2.2 takes a similar strategy ?
