 unexpected IO-APIC on IBM xSeries 440
Hi list,
as instructed I'm making contact (attached dmesg). IBM claims that machine
is supported under linux (RedHat Advanced Server 2.1) but I couldn't find any
patches. Is it possible that RedHat is hiding some patches from linux
community? :)

The problem is that /proc/cpuinfo shows at most 4 processors (depending on
kernel version). Dmesg shows many  "APIC error on CPUx: 00(80)" errors.
I can provide you with further details (make some tests) if needed.

Kernel is preemptible and is compiled with bigmem and acpi enabled.

prerelease)) #2 SMP czw wrz 12 16:32:16 CEST 2002

 unexpected IO-APIC on IBM xSeries 440

Hardly. The patches for pretty much every vendor tree are neatly broken
down at http://www.kernelnewbies.org/

I don't know what state 2.5 is on Summit numa but 2.4.19-ac and
2.4.20pre6 plus one patch (I can bounce you the diff if you want) should
work nicely on summit chipsets with any distro

2.5 has some problems with interrupts and ACPI that were being
worked around ... the right people here will send you some stuff.
