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...
