?I wrote about this a couple months back.? George asked me to submit to the Xen
developers list, but I never had the time due to work demands on getting the new
server set up.? In my case, I had to use a different server.? The new
motherboard/CPU had no issues with the second CPU.? If you turn off and unplug
the second CPU, it will work.
Check the archives for my e-mail address and see George's replies.? If you
can follow through with reporting it, that would be great.
