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" ;). -- Klaus Muth HAGOS eG Industriestr. 62 fon: (+49) 711 78805-86 EDV-Programmierung 70565 Stuttgart fax: (+49) 711 78805-35 http://www.hagos.de Germany mailto:muth-5lHx5lHeYlQ@public.gmane.org ------------------------------------------------------- This SF.Net email is sponsored by: NEC IT Guy Games.
