Description

A little addition. I have the lines in my dmesg: ACPI BIOS Error (bug): A valid RSDP was not found (20130823/tbxfroot-223) ACPI: Table initialisation failed: AE_NOT_FOUND ACPI: Try disabling either ACPI or apic support. It looks like agp_generic_attach is trying to create two device nodes both named "/dev/agpgart" with no unit numbers. That's a no-no, which is why you're getting EEXIST (errno 17). As a workaround, try disabling merely one of your two AGP devices. That will probably fix the panic. The next question is: why do you have two AGP devices? Created attachment 145022 [details]
test patch for 9-STABLE.
This problem also occurs my computer that is used Intel 855 GME chipset.
This problem also occurs in versions below.
9.3-RELEASE
9.2-RELEASE
10.0-RELEASE
9-STABLE
And I expect it also occurs in CURRENT, but I have not checked it yet.
The patch can avoid panic. And some informations are added to dmesg.boot.
Quote of part of the dmesg.boot:

Perhaps, agp0 is calling agp_generic_attach from sys/dev/agp/agp_intel.c. and agp1 is calling agp_generic_attach from agp_generic_attach from sys/dev/agp/agp_i810.c. But /dev/agpgart is already exists in second time of calling agp_generic_attach.
Perhaps, this patch's agpgart is referring to agp0. It is not right.

test patch for 8-STABLE
8.4-RELEASE and 8.4-STABLE has same problem. But 8.4 doesn't cause panic.
Because devfs of 8.4 allows make duplicate entry.

sc->as_devnode refers to a different pointer. I do not know how it work correctly.
10.1-BETA1 r271727 couldn't be booted. But It could be booted after typing below on loader prompt set hint.agp.0.disabled=1 boot-conf Encountering the same kernel panic with FreeBSD 10.1 RC3 installer (memstick img) (screenshot) http://pix.toile-libre.org/upload/original/1414061308.jpg Same intel 855GME adapter, on an Xploretech ix104c3 tablet PC. Booting with hint.agp.0.disabled=1 helped go further, but then I had to disable ACPI as well otherwise another type of kernel panic occured. Now blocked at "still waiting xpt_config" messages. If more details needed please ask (I'm new to FreeBSD). My 855GME is needed to write lines below to boot 10.2-RELEASE because agp2 is appeared. hint.agp.0.disabled=1 hint.agp.2.disabled=1 I appear to have been bitten by the same bug in 10.2-RELEASE Interestingly it did not happen in 10.1-STABLE but occurs in 10.2 RELEASE and 10.3 at least up to Revision 294986 (what I tested today) Putting this line (as suggested below) in loader.conf worked: hint.agp.1.disabled=1 The backtrace: agp1: <Intel 82855GME (855GME GMCH) SVGA controller> on vgapci1 panic: make_dev_sv: bad si_name (error=17, si_name=agpgart) cpuid = 0 KDB: stack backtrace: #0 0xc0b79682 at kdb_backtrace+0x52 #1 0xc0b3a1ab at vpanic+0x11b #2 0xc0b3a08b at panic0x1b #3 0xc0adf593 at make_dev_sv+0x2f3 #4 0xc0adf61a at make_dev+0x7a #5 0xc0571514 at agp_generic_attach+0x124 #6 0xc0f573eb at agp_i810_attach+0x7b #7 0xc0b6fd94 at device_attach+0x474 #8 0xc0b70e2b at bus_generic_attach+0x2b #9 0xc08669ca at vga_pci_attach+0x4a #10 0xc0b6fd94 at device_attach+0x474 #11 0xc0b70e2b at bus_generic_attach+0x2b #12 0xc055175b at acpi_pci_attach+0x18b #13 0xc0b6fd94 at device_attach+0x474 #14 0xc0b70e2b at bus_generic_attach+0x2b #15 0xc05543dc at acpi_pcib_attach+0x25c #16 0xc05543dc at acpi_pcib_acpi_attach+0x2ec #17 0xc0b6fd94 at device_attach+0x474 (In reply to tookmund from comment #8) I forgot to add that I am using a Thinkpad R51 I'm experiencing this in 10.3 Release on a Toshiba Satelite L10-104. The hints respectively patches mentioned make it boot. However it crashes when starting xorg with the intel driver. It works with the vesa driver, but I need hardware acceleration (2D is OK, no need for OpenGL). Anybody ever running FreeBSD with xorg and the Intel driver on a 855GM successfully? (In reply to dominik.muth from comment #10) For completeness I attached my patch for 10.3-RELEASE. It add unit numbers to the agpgart device files to resolve the naming conflict.

Patch for FreeBSD 11 to remove kernel panic and number agpgart devices
I was affected when I installed FreeBSD 11 on a 2004 Toshiba laptop with an Intel 855 graphics chip and an external VGA port. There was a kernel panic as the PCI bus was checked for devices. Each graphics port has a separate set of memory addresses and shows up separately during the PCI probe.
The patch uses make_dev_s with MAKEDEV_CHECKNAME to prevent a kernel panic if something goes wrong but includes logging and state cleanup on error.
The patch creates /dev/agpgart for the first AGP device found on the bus and numbers each unit after that (/dev/agpgart2, ...).
Without the patch, the work-around is to stop the boot loader and enter the following commands:
set hint.agp.1.disabled=1
boot
Once booted, the following line is added to /boot/loader.conf:
hint.agp.1.disabled=1
These fixes have been tested with X11 and a dual monitor setup.

Automatic reboot in 15 seconds - press a key on the console to abort
By the way, how many PCs are affected by this bug in the whole world? My 855GME will no longer boot. orz I was just bit by this on my ancient Sony Vaio. Tried both 12.0 and 11.2 snapshots as of April 11, 2019. Machine was booting happily with 8.2, listing two vgapci-devices: vgapci0: <VGA-compatible display> port 0x1800-0x1807 mem 0xe8000000-0xefffffff,0 xe0000000-0xe007ffff irq 9 at device 2.0 on pci0 agp0: <Intel 8285xM (85xGM GMCH) SVGA controller> on vgapci0 agp0: detected 3964k stolen memory agp0: aperture size is 128M vgapci1: <VGA-compatible display> mem 0xf0000000-0xf7ffffff,0xe0080000-0xe00ffff f at device 2.1 on pci0 The original work-around helped avoid the panic. And now I am also blocked by the xpt_config's endlessly looping -- as was mentioned in Comment #6 five years ago... (In reply to fred+freebsdbugzilla from comment #6) https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=136327 discusses the xpt issue. Created attachment 204441 [details] Panic screenshot: 10.1 RC33 Intel 855GME Attach screenshot from comment 6 in case it goes away We need an updated patch against latest CURRENT confirmed to resolve the issue dumbbell and kib may be able to help given graphics expertise and (not quite so recent) commits to this area of the tree. /dev/agpgart must point to real agp instead of the ghost sibling, but the order of enumeration is not strictly defined. So I think that both nodes should be created as /dev/agpgart0 and /dev/agpgart1, and then a symlink, the alias device in devfs term, created to point to one of them. Perhaps use pci function number as the unit number, and them symlink to function 0. I wonder if Gen3 or earlier hw work with the current off-tree drm kmod. If it does not, then perhaps this report should be closed as 'not fix'. (In reply to Konstantin Belousov from comment #21) I have a hardware that I run 13-current, I need and have been using loader.rc work-around, and switched to use ports' DRM module. I have last updated around March 2019. I can help testing. I can test as well. Compaq Presario 2200 notebook with Intel 845GM soldered into on-board AGP. Kernel panic still happens in 12.0-p5 without the workaround. Comment on attachment 145022 [details]

Overcome by events. The patch for -11 should still be applicable.
Is the patch being taken? It will be nice if a system works without a work-around. Can someone take a look at this? This has been long standing and also multiple fixes have been suggested. I started using pxeboot and pxeboot doesn't seem to loder.conf. As a result, a machine started crashing; it requires setting hint.agp.1.disabled=1 at loader prompt every time. laptop Fujitsu S6120 FreeBSD 13.0-RELEASE-i386-memstick.img needs set hint.agp.1.disabled=1 at boot loader prompt in order to boot without kernel panic.
