Subject: [2.6.17.11] strange pcie errors/warnings on Abit KN9-SLI mainboard

Hello,

(running 2.6.17.11 vanilla on Debian SID)

I recently acquired a new pc, with an ABIT KN9-SLI mainboard, using an AMD64x2 
AM2 processor.

System boots fine, but I have some messages/errors in the dmesg that I'm worried 
about. Googling around for them didn't really show up much.

First:

Aug 27 15:35:04 whocares kernel: PCI-DMA: Disabling IOMMU.

IOMMU is (as far as I can see) enabled:
whocares:/var/log# cat /usr/src/build/linux-2.6/.config | grep IOMMU
CONFIG_GART_IOMMU=y

I can't really determine if this is normal. According to the code it seems that 
this is disabled by default when you don't have AGP? (I'm not a kernel-coder, so 
I may be very wrong on this)

Second:

Aug 27 15:35:04 whocares kernel: PCI: Setting latency timer of device 0000:00:0a.0 to 64

Any ideas what might be wrong? If anything is wrong, that is.

Thanks!

Jan
