Thanks for all you help Alan,
I think at this point my Linux kernel debugging knowledge has run
aground. I would
love to crack this nut, but I doubt that will be possible with my
current knowledge base.
For now I am going to run the patched kernel even if I don't
understand precisely why
they prevent the box from hanging on boot when the Comtrol card is present.
