I use standard Debian kernels, .config and dmesg outputs available at: http://liafa.jussieu.fr/~jcristau/tmp/dmesg-2.6.16 http://liafa.jussieu.fr/~jcristau/tmp/dmesg-2.6.17 http://liafa.jussieu.fr/~jcristau/tmp/config-2.6.16-2-686 http://liafa.jussieu.fr/~jcristau/tmp/config-2.6.17-1-686 Kernel 2.6.17 suggests to use pci=assign-busses, but that doesn't seem to change anything. Output of "lspci -vvvxxx" under 2.6.16 is attached.
