SubjectProbably buggy MP Table and ACPI doesn't works
Hi, I've compiled my kernel with Local APIC and IO-APIC function on a 
UniProcessor system (MSI KT4 Ultra + Athlon 2400+) and at the system
start I see this (kernel 2.4.21-pre3-ac4 , but is similar with all the
kernels) :

What does mean buggy MP table on device 00.11.1 ?? (That is the IDE
controller I think) In my bios I can select 1.4. and 1.1. MPS table,
I've tried both but the situation doesn't change. This messsage is
appeared recently , with the bios upgrade from 1.1 to 1.3. Doing lspci
-vvvxxx I've noticed that the IRQ of 00.11.1 is routed to IRQ 0 .

And there is another problem. With IO-APIC activated in the kernel ACPI
works in a strange way. I can't shutdown the system by pressing the
On/Off button, and when I do "shutdown -h now" the system instead to
halt it reboots . I hear the HD that are Off, but the fans and the PSU
remain Switch On, after few seconds the HDs switch on again and the
system restarts. Why??

If I disable IO-APIC and use Local APIC only ACPI works correctly, but I
recive the message "spurious 8259A interrupt: IRQ7" during the boot or
few time later after the boot. Should I disable APIC at all?? This
problem of ACPI is present with 1.1 bios too

Thanks

Bye

Marcello
