Subject: unexpected IO-APIC when booting

Hello.
I am not on this list so if you need to respond to me please email me
directly.
In booting my stock RH70 kernel I got the attached message.
The machine is a Dell Precision 420 Workstation. It is a dual P3-800 with
1gb of PC800 RDRAM. The kernel is the stock RH70 SMP kernel.
The message said I should email this list about the unexpected IO-APIC.
Also, my dnetc client has started running on only one processor instead of
two processors. Two crunchers start but only run on one processor.
Yesterday (when I installed RH on this machine) dnetc was running on both
processors. I am not sure if the IO-APIC could be affecting this.
Once again, please email me directly.
Thanks.
