Hi list,
I've been playing around with Xen for a few months now, and I'm very
excited about this product.
A few days ago I started a fresh install on an Compaq Proliant DL580.
It's the first generation of this machine with 4x p3 700 Mhz (1mb cache btw)
The dom0 is using Debian 3.1 (sarge) and works perfectly.
Only after installing xen, and booting xen, I'm getting a _lot_ of the
following messages after a while:

There aren't any domU's running yet. And after a while I've noticed that
this error occurs on every cpu, except CPU 0 ?
I also found this short conversation in the mailing list, but are
curious if there is any news on this subject.
http://groups.google.nl/group/xen-devel-archive/browse_thread/thread/6391b9fc16f3b591/1b41dff3f57e9186?lnk=st
Keir also suggests to "turn off" the messages, but is this a solution or
just a workaround ?
I also tried running it on a different p3 xeon box (with 2 processors)
and got the same errors.
Then I tried running the same config on a normal p4 desktop pc, and I
got no errors at all.
I hope someone has any ideas or suggestions of what this problem might
cause, or can tell me what I'm missing here.
Thanks in advance,
Hugo Rodenburg
