State Changed From-To: open->feedback You disable everything except the keyboard? That sounds like a recipe for disaster. :-) Try not disabling anything. If you believe that there are device probes that get confused by your hardware, disable those. Let us know how it goes. This problem occurred on my machine. Machine is : FUJITSU GRANPOWER 5000 model760 / model560, 2 x PentiumPro 200MHz (but not SMP kernel), 450GX (Orion) chipset (Intel 82453KX/GX), 2 x AIC7880 SCSI, Mylex DAC960P RAID Controler (model760 only) This machine seems Intel AP450GX/AR450GX motherboard OEM. ( http://support.intel.com/support/motherboards/server/AP450GX/ ) This machine can boot with FreeBSD 3.x and FreeBSD 5-current-20000805. Only FreeBSD 4.1-{RELEASE,STABLE} kernel fails to boot. It seems to me that FreeBSD 4 kernel's PCI bus probe fails on 450GX chipset and the machine hangs up. (maybe in src/i386/isa/pcibus.c) To fix, apply following msmith's commit to RELENG_4. |Message-Id: <200004162048.NAA83339@freefall.freebsd.org> |From: Mike Smith <msmith@FreeBSD.org> |Date: Sun, 16 Apr 2000 13:48:34 -0700 (PDT) |To: cvs-committers@FreeBSD.org, cvs-all@FreeBSD.org |Subject: cvs commit: src/sys/boot/common help.common src/sys/conf | options.i386 src/sys/i386/conf LINT src/sys/i386/i386 bios.c | src/sys/i386/include/pc bios.h src/sys/i386/isa pcibus.c | |msmith 2000/04/16 13:48:34 PDT | | Modified files: | sys/boot/common help.common | sys/conf options.i386 | sys/i386/conf LINT | sys/i386/i386 bios.c | sys/i386/include/pc bios.h | sys/i386/isa pcibus.c | Log: | Some more i386-only BIOS-friendliness: | | - Add support for using the PCI BIOS functions for configuration space | accesses, and make this the default. | | - Make PNPBIOS the default (obsoletes the PNPBIOS config option). | | - Add two new boot-time tunables to disable each of the above. | | Revision Changes Path | 1.15 +8 -0 src/sys/boot/common/help.common | 1.135 +1 -4 src/sys/conf/options.i386 | 1.770 +1 -3 src/sys/i386/conf/LINT | 1.30 +18 -14 src/sys/i386/i386/bios.c | 1.8 +12 -1 src/sys/i386/include/pc/bios.h | 1.58 +113 -10 src/sys/i386/isa/pcibus.c I rebuild 4.1-STABLE kernel with following 5-current's sources, and it works fine.

Thank you, Fukui-san.
We'll leave the PR in ``feedback'' state until the originator can test
your suggestion and comment.
Ciao,
Sheldon.
My machine cannot boot with 4.1.1-RELEASE as before. I'm inconvenienced. >On Tue, 08 Aug 2000 14:12:03 +0900, Masayuki FUKUI wrote: > >> It seems to me that FreeBSD 4 kernel's PCI bus probe fails on 450GX chipset >> and the machine hangs up. >> (maybe in src/i386/isa/pcibus.c) I tried to find the cause and probably found it. In src/sys/i386/isa/pcibus.c nexus_pcib_identify(), | retry: | for (probe.slot = 0; probe.slot <= PCI_SLOTMAX; probe.slot++) { | probe.func = 0; | hdrtype = pci_cfgread(&probe, PCIR_HEADERTYPE, 1); On unavailable PCI slot, 'hdrtype' is always 0xff (-1).

I don't know why... (or 450GX chipset's bug?) (When 'probe.slot' is 31 and 'probe.func' is 6, it returns from 'pci_cfgread()' and 'id' is 0xffffffff (-1).) I don't know how to fix rightly. But I rebuild 4-STABLE kernel with following patch, and it works fine. I hope for fixing the probrem as soon as possible. --- src/sys/i386/isa/pcibus.c.orig Thu Feb 24 05:25:06 2000 +++ src/sys/i386/isa/pcibus.c Sun Oct 1 23:16:06 2000 @@ -439,6 +439,7 @@ int found = 0; int pcifunchigh; int found824xx = 0; + int found_orion = 0; if (pci_cfgopen() == 0) return; @@ -448,7 +449,7 @@ for (probe.slot = 0; probe.slot <= PCI_SLOTMAX; probe.slot++) { probe.func = 0; hdrtype = pci_cfgread(&probe, PCIR_HEADERTYPE, 1); - if (hdrtype & PCIM_MFDEV) + if (hdrtype & PCIM_MFDEV && (!found_orion || hdrtype != 0xff) ) pcifunchigh = 7; else pcifunchigh = 0; @@ -483,6 +484,8 @@ found = 1; if (id == 0x12258086) found824xx = 1; + if (id == 0x84c48086) + found_orion = 1; } } } State Changed From-To: feedback->closed Patch to PCI configuration space scan committed after discussion with Fukui-san.
