Hi!

Ok, I do the Ingrid.

Yeah, this is the problem. I downgraded the BIOS, now the kernel uses ACPI:

ACPI: RSDP (v000 IBM ) @ 0x000fdfc0
ACPI: RSDT (v001 IBM SERONYXP 0x00001000 IBM 0x45444f43) @ 0xbffcf780
ACPI: FADT (v001 IBM SERONYXP 0x00001000 IBM 0x45444f43) @ 0xbffcf700
ACPI: MADT (v001 IBM SERONYXP 0x00001000 IBM 0x45444f43) @ 0xbffcf640
ACPI: MCFG (v001 IBM SERONYXP 0x00001000 IBM 0x45444f43) @ 0xbffcf600
ACPI: DSDT (v001 IBM SERGEODE 0x00001000 MSFT 0x0100000b) @ 0x00000000
ACPI: PM-Timer IO Port: 0x588
ACPI: Local APIC address 0xfee00000
ACPI: LAPIC (acpi_id[0x00] lapic_id[0x00] enabled)
[and so on]

and acpidmp:

RSDP "IBM" @ 0x000fdfc0
0000: 52 53 44 20 50 54 52 20 77 49 42 4d 20 20 20 00 RSD PTR wIBM .
0010: 80 f7 fc bf

Is it possible, that IBM did update the version without updating the checksum?
Now, that I downgraded the BIOS, the x236 runs like a charm with 4 processors
and all PCI interrupts routed correctly ;). I strongly suspect now, that the
linux acpi code is correct with saying "Checksum error" ;).
