Sorry, I don=E2=80=99t know why miss Description, and How-To-Repeat.
Here, I add it.
1. Description:
Hello FreeBSD team.
In June, I upgraded to 8.1 prerelease amd64, All work fine.
But I upgraded 8.1-STABLE amd64 yesterday, Cause kernel panic when
kernel use ifconfig to confgure iwn device.
Note: From 8.0, always /usr/src/sys/dev/acpica/acpi_pcib_acpi.c apply
ACPI patch for TOSHIBA
Under is panic log message...
Fatal trap 12: page fault while in kernel mode
cpuid =3D 1; acpi id =3D 01
fault virtual address =3D 0x18
fault code =3D supervisor read data, page not present
instruction pointer =3D 0x20:0xffffffff8026546a
stack pointer =3D 0x20:0xffffff80751df810
frame pointer =3D 0x20:0xffffff80751df870
code segment =3D base 0x0, limit 0xfffff, type 0x1b

processor eflags =3D interrupt enabled, resume, IOPL =3D 0
current process =3D 57286 (ifconfig)
trap number =3D 12
panic: page fault
cpuid =3D 1
Uptime: 18s
Cannot dump. Device not defined or unavailable.
Automatic reboot in 15 seconds - press a key on the console to abort
panic: bufwrite: buffer is not busy???
cpuid =3D 1
=3D=3D=3D End of panic log message =3D=3D=3D
If I remove "device iwn" in mya kernel config file, Work fine.
If need more information or debug, Please tell me
Thanks very much.
2.How-To-Repeat:
kernel config file
"device iwn"
exist.
Please add to PR
Thanks very much.
