--- Comment #17 from Mikhail Teterin  ---
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:  port 0x1800-0x1807 mem
0xe800-0xefff,0
xe000-0xe007 irq 9 at device 2.0 on pci0
agp0:  on vgapci0
agp0: detected 3964k stolen memory
agp0: aperture size is 128M
vgapci1:  mem
0xf000-0xf7ff,0xe008-0xe00
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...

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.

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?

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

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).

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:

pcib0: ACPI Host-PCI bridge port 0xcf8-0xcff on acpi0
pci0: ACPI PCI bus on pcib0
agp0: Intel 82855GM host to AGP bridge on hostb0
agp0:  make_dev agpgart for 0x35808086 
agp0:  sc-as_devnode: 0xc52e9c00 
agp0:  sc-as_devnode-si_drv1: 0 
agp0:  sc-as_devnode-si_drv1: 0xc52e8980 
pcib1: PCI-PCI bridge at device 1.0 on pci0
pci1: PCI bus on pcib1
vgapci0: VGA-compatible display port 0x1800-0x1807 mem
0xe800-0xefff,0xe000-0xe007 irq 9 at device 2.0 on pci0
agp1: Intel 82855GME (855GME GMCH) SVGA controller on vgapci0
agp1:  make_dev agpgart for 0x35828086 
agp1:  sc-as_devnode: 0 
agp1: aperture size is 128M, detected 8060k stolen memory
vgapci0: Boot video device
vgapci1: VGA-compatible display mem
0xf000-0xf7ff,0xe008-0xe00f at device 2.1 on pci0

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.
