Ah, so the reconects do not happen often enough to tell immediately
whether switching kernels caused relief?

We need a program to automatically create histograms with number of
occurences per day, per hour, and per minute for intermittent bugs like
this one. :)

The new data from this last observation is that 3.2.2-1 is capable of
producing random reconnects and instability, just like the newer
kernels.  So the mystery of the 3.2.2 -> 3.2.9 regression has been
dispelled.

I don't expect 3.2.21-1 to be any different from, say, 3.2.18-1, so I
don't think it's worth spending much time with it loaded unless
there's no better test to run.  I can suggest a kernel if you'd like,
or if you want to use whichever has worked best in the past (3.4.y?)
until we haved spent a little more time mulling over the data you've
already provided, that's fine with me, too.

Hope that helps,
Jonathan
