ACPI on Intel SE7501WV2

ACPI on Intel SE7501WV2

[Bernard Normier]

The Intel SE7501WV2 is a dual Xeon server motherboard. 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

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:

Interestingly, disassembling /proc/acpi/dsdt with iasl shows the same

and if I try to compile this dsdt.dsl with iasl -ta, I get this error:

Can I safely ignore all these warnings, since I don't use power management 
on these servers?

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

Thanks,
Bernard

What's the result if you disable 'CONFIG_PCI_MSI'?

The error message possibly isn't harmful. Please latest kernel.

I tried to disable USB legacy support in the BIOS, but it did not make any 
difference.
USB support is not important for me, so I'd rather switch off USB and keep 
ACPI for hyper-threading.

Any suggestion for the other warnings?

Thanks,
Bernard

I did not try; I can live without USB.

I hope these warnings are indeed harmless! I also get them with 2.6.9-rc3; 
which kernel do you suggest?

Thanks,
Bernard
