Public bug reported:

Binary package hint: linux-image-2.6.15-23-amd64-k8

These are known problems, as far as I can understand. But another report
may be of at least some little interest.

The mainboard is a nForce3 250 chipset on a Gigabyte K8 Triton series,
GA-K8NS board with an AMD 2800+ Semron CPU.

Could the DMA problem be connected with:

...missing nForce3/4 storage controller device IDs
(see)
http://download.nvidia.com/XFree86/nforce/1.0-0306/KnownProblems.html

I also have a vague unreliable memory of the AGP problem being fixed
with the very latest kernel.

The latest Ubuntu kernel update does not fix these problems. I have
downloaded the kernel source from Ubuntu and will attempt to read it and
attempt to add fix patches, if I can find any... but, having a chronic
illness which adversely affects memory and concentration as well as
severe fatigue I wouldn't wait for me to do this... it could take
months, assuming I can even get it together enough to patch and compile
a kernel, which is uncertain.

I hope the below excerpts are enough information. (I doubt if a lspci
will be of any benefit. I can be contacted at
ccjonesatceinternetdotcomdotau if need be.)

The sections of the output from the boot messages are as follows:

First the AGP problem:
 Checking aperture...
[    0.000000] CPU 0: aperture @ f8000000 size 32 MB
[    0.000000] Aperture from northbridge cpu 0 too small (32 MB)
[    0.000000] AGP bridge at 00:00:00
[    0.000000] Aperture from AGP @ f8000000 size 4096 MB (APSIZE 0)
[    0.000000] Aperture from AGP bridge too small (0 MB)
[    0.000000] Your BIOS doesn't leave a aperture memory hole
[    0.000000] Please enable the IOMMU option in the BIOS setup
[    0.000000] This costs you 64 MB of RAM
[    0.000000] Mapping aperture over 65536 KB of RAM @ 4000000

(and later, deleting APIC setting here)

 30.564349] agpgart: Detected AGP bridge 0
[   30.564886] agpgart: Aperture conflicts with PCI mapping.
[   30.564956] agpgart: Aperture from AGP @ f8000000 size 4096 MB
[   30.565010] agpgart: Aperture too small (0 MB)
[   30.565060] agpgart: No usable aperture found.
[   30.565111] agpgart: Consider rebooting with iommu=memaper=2 to get a good aperture.
