Date: Mon, 28 Aug 2006 07:55:55 +0200 From: Jan De Luyck <ml_linuxkernel_20060528@...re.org> To: linux-kernel@...r.kernel.org 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 Aug 27 15:35:04 whocares kernel: pcie_portdrv_probe->Dev[0376:10de] has invalid IRQ.

If anything is wrong, that is. Thanks!
