I just retried this today (after noting a new tag upstream, I was
thinking I have not seen this in a while) and was unable to reproduce
the problem using the suspend feature. I note that I now have a 3.2
kernel and see some info on jumbo frames in my dmesg. No other notable
changes jump out at me in the outputs below.
