diff -u for mkinitrd, isapnp.c, and isapnp_proc.c
Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/ |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1) Gecko/20031030 Description of problem: isa-pnp configuration happens too late if at all. If the module is loaded from linuxrc on the initrd, no post-install gets run and no configuration takes place. /etc/rc.sysinit skips isapnp configuration if the /proc interface exists. What needs to happen is mkinitrd needs to convert post-install's that cat > /proc/somewhere into a series of echo > /proc/somewhere (since cat does not exist on initrd). mkinitrd also needs to mount /proc before loading modules instead of after as it does now. In addition, isa-pnp needs to accept multiple command fragments on a single line. Currently it expects "card", "port", "dma", "irq" settings on separate lines. I propose adding ';' to the '\n' terminator test to combine the fragments on a single line. I propose using "#Begin" and "#End" comments in the catted config file to tell mkinitrd how to block the fragments. nash and isapnp_proc.c don't agree on which open modes are writable. nash's echo > file opens file read/write (which is wrong) and isapnp_proc expects either readonly or writeonly, rejecting readwrite. I propose making isapnp_proc more tolerant as long as there are other changes going in. While reformatting the output from /proc/isapnp, making it suitable for input to itself, the way isapnptools was, makes updating configurations much easier. I'd also like a different order for interrupt allocation, starting with least frequently used and saving popular ones for later. Giving away 5 and 10 early makes activating sound cards difficult or impossible. Version-Release number of selected component (if applicable): .4.22-1.2174.nptl How reproducible: Always Steps to Reproduce: 1.Hardware configuration needs a printer, isapnp lan card, sb16 with attached cdrom 2.isapnp_reserve_irq=7 # for printer 3.reboot Actual Results: 4.ide driver uses default irq 10 for ide3 (sb16 cdrom) 5.isapnp allocates irq 5 to the lan card 6.modprobe sb complains about out of resources Expected Results: setting either the sb16 to ide1 or ide2 in /etc/isa-pnp.conf would allow the sb audio device to load. Changing the interrupt allocation to use 12, 15, 11, before 5 or 10 would also allow the sb to load. (sb uses irq 5/7/10 only) Additional info: I have suggested patches for mkinitrd, isapnp.c, and isapnp_proc.c that I will upload once this is in the database.
