Hi! I finally managed to build and boot a -stable test kernel on my -current system. There was a mismatch between a header file in /sys/pci and some use of a structure defined therein from /sys/i386/isa/pcibus.c, which had caused interrupt registration to fail with the version I had sent out as a beta of this code before. In order to automatically load PCI LKMs at system startup, I suggest to make the following changes to the startup scripts: 1) Modify /etc/rc to source /etc/rc.lkm, if present 2) Add /etc/rc.lkm, which is a NOP unless /lkm/pci/lkm.map exists 3) Create an empty /lkm/pci (-> mtree) 4) Add a sample lkm.map file, which explains that the format is to have a PCI device/vendor ID in hex in the first column, and the LKM name (without the trailing .o) as the second. Is anybody opposed to these changes ? Are there any further suggestions ? I plan to commit these changes tomorrow!
