https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=187015 tatsuki_makino@hotmail.com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |tatsuki_makino@hotmail.com --- Comment #3 from tatsuki_makino@hotmail.com --- Created attachment 145022 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=145022&action=edit 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 0xe8000000-0xefffffff,0xe0000000-0xe007ffff 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 0xf0000000-0xf7ffffff,0xe0080000-0xe00fffff 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. -- You are receiving this mail because: You are the assignee for the bug.
