This is a specific problem of your chip set. Vendor ID = 10B9, that is ACER LABS according to my PCI vendor list ... Problem is, that there are quite a number of broken chip sets, and the latest Compaq chip set violates a very clearly stated requirement of the PCI 2.0 specs. Working around that bug means weakening some consistency test, which now seems to succeed on your board, though it doesn't offer that particular feature. } do you want me to do some specific tests ? Yes, please do so! I need VERBOSE boot messages from the failing kernel. You may be able to obtain them by booting that kernel with: Boot: /kernel.old -v (if you have kept the kernel with the defective version of pcibus.c under that name). After the boot failed, you can hit reset and boot the working kernel. Now type '/etc/dmesg' and look for messages left over from the FIRST boot. If there aren't any (I need everything starting from some 6 lines above "Probing for devices on the PCI bus"), then you'll have to write down the lines starting with either pcibus_setup or pcibus_check. (I need all numbers, the text is constant ...) I'd really appreciate, if you sent these lines! After I received those messages, I might be able to write a fix, which ought to make the probe work again, and I'd need you to test it on your machine. Thanks for offering help to get this resolved!
