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!

Hi,
unless you have >= 4Gb of ram you don't need an IOMMU (in fact using it
would only cause extra overhead)... so the kernel will not use it in
that case.

Any other messages? In addition to the above, I get:
PCI: Cannot allocate resource region 7 of bridge 0000:00:04.0
PCI: Cannot allocate resource region 8 of bridge 0000:00:04.0
PCI: Cannot allocate resource region 9 of bridge 0000:00:04.0
PCI: Cannot allocate resource region 7 of bridge 0000:00:05.0
PCI: Cannot allocate resource region 8 of bridge 0000:00:05.0
for my two pcie bridges.
Also please post 'lspci -v' output for one of the problem devices.

Nope, I'm not seeing those.
I have the messages for all my pcie bridges. Here's the lspci output:
