Power management is not a concern ... but stability is. When I boot with 2.6.8-1.521smp (latest Fedora Core 2), or my own 2.6.9-rc3 smp kernel build, the log shows 2 ACPI-related issues: - with USB enabled in the BIOS, dmesg shows: hub 2-0:1.0: USB hub found hub 2-0:1.0: 2 ports detected irq 169: nobody cared! (screaming interrupt?) irq 169: Please try booting with acpi=off and report a bug [<021074d6>] __report_bad_irq+0x3a/0x77 [<02107572>] note_interrupt+0x43/0x66 [<021078c4>] do_IRQ+0x19d/0x225 handlers: [<0225a679>] (usb_hcd_irq+0x0/0x4b) Disabling IRQ #169 If I disable USB support in the BIOS, this error goes away. That's ok for me, since I don't use the USB ports on these servers. - I always get these warnings: PCI: PCI BIOS revision 2.10 entry at 0xfdb75, last bus=4 PCI: Using configuration type 1 mtrr: v2.0 (20020519) ACPI: Subsystem revision 20040326 ACPI-0562: *** Warning: Type override - [DEB_] had invalid type (Integer) for Scope operator, changed to (Scope) ACPI-0562: *** Warning: Type override - [MLIB] had invalid type (Integer) for Scope operator, changed to (Scope) ACPI-0562: *** Warning: Type override - [DATA] had invalid type (String) for Scope operator, changed to (Scope) ACPI-0562: *** Warning: Type override - [SIO_] had invalid type (String) for Scope operator, changed to (Scope) ACPI-0562: *** Warning: Type override - [LEDP] had invalid type (String) for Scope operator, changed to (Scope) ACPI-0562: *** Warning: Type override - [GPEN] had invalid type (String) for Scope operator, changed to (Scope) ACPI-0562: *** Warning: Type override - [GPST] had invalid type (String) for Scope operator, changed to (Scope) ACPI-0562: *** Warning: Type override - [WUES] had invalid type (String) for Scope operator, changed to (Scope) ACPI-0562: *** Warning: Type override - [WUSE] had invalid type (String) for Scope operator, changed to (Scope) ACPI-0562: *** Warning: Type override - [SBID] had invalid type (String) for Scope operator, changed to (Scope) ACPI-0562: *** Warning: Type override - [SWCE] had invalid type (String) for Scope operator, changed to (Scope) ACPI: Interpreter enabled Interestingly, disassembling /proc/acpi/dsdt with iasl shows the same warnings/errors.

If you'd like more details (such as the full dmesg, dmidecode output) I'd be happy to send them.
