The pnp code likely needs to become smarter so that when presented with a pnp device that is has the same resources as the hardwired devices, the hardwire should "win" if you will (eg, fdc0 should attach pnp or no and there shouldn't be a fdc1 that attaches to pnp and then the nonpnp one fails to attach).

Re: The Commit That Broke PCM
OK, the bad news is that reverting to pcm of Dec 5 doesn't fix my problem. The good news is that "options PNPBIOS" does fix it. Now if only someone could explain all this junk: # pnpinfo Checking for Plug-n-Play devices...

The Commit That Broke PCM
PCM has been broken for me since December 1999. I would very much appreciate if someone could help me fix it before the code freeze (cg, dfr and tanimura CC'd). I have an unknown MSS-compatible non-PnP ISA sound card, which identifies itself as a CS4231. Unknown, because it's inside a laptop. Before you ask, it has always been identified as a CS4231, and always worked very well. The last kernel that I have which still works is dated 6 Dec 1999, and I'm playing mp3's with it right now. Here's its verbose boot message: mss_detect - chip revision 0x0a mss_detect() - Detected CS4231 pcm0: at port 0x530-0x53f,0x310-0x311 irq 5 drq 1 flags 0xa210 on isa0 pcm: setmap 3, ff00; 0xc8421000 -> 3 pcm: setmap 4, ff00; 0xc8431000 -> 4 isa_probe_children: probing PnP devices Kernels built after 26 Dec 1999 print the following: mss_detect - chip revision 0x0a mss_detect() - Detected CS4231 pcm0: at port 0x530-0x537,0x538-0x539 irq 5 drq 1 flags 0xa110 on isa0 pcm: setmap 3, ff00; 0xc840e000 -> 3 pcm: setmap 4, ff00; 0xc841e000 -> 4 isa_probe_children: probing PnP devices mss_intr: irq, but not from mss and screw up the card - there is no sound and the driver gets stuck in "pcmwr". Something was committed between the 6th and 26th of December that broke pcm. The question is: which commit broke it? What has changed? 1) I/O port allocation and flags in dmesg: 0x310-0x311 vs 0x538-0x539, and 0xa210 vs 0xa110 2) The "mss_intr: irq, but not from mss" line Why? My config file hasn't changed a bit, neither has my hardware or BIOS setup.I don't have "controller pnp" in my config file, so it probably has nothing to do with PnP. The list of commits that might have broken it is appended below for your convenience. Please let me know if I have missed something obvious.
