I just went ahead and backed out the problematic change. Haven't even
tried building the code yet - but if you feel lucky, it's up. I bet it
fixes it.

Hi Kent,

I pull down your latest code and did a build. I'm pleased to say that
Windows has now installed. I will do some further testing/benchmarking
to make sure that the install is stable.

Many thanks for your quick help

Hi Kent,

A little bad news. With this new build, the spindles are getting
thrashed and this is constantly (never stopping) spewing out on my
netconsole:

Any ideas?

Looks like the same problem I reported in April.
