FreeBSD feynman.ham01.thiemo.net 5.3-BETA6 FreeBSD 5.3-BETA6 #2: Thu Oct 7 14:59:18 CEST 2004 thiemo@feynman.ham01.thiemo.net:/usr/src/sys/i386/compile/FEYNMAN i386
Hardware is HP Pavilion zt3312ea, affected interface is:
Intel PRO/Wireless 2200BG Network Connection.
Windows driver used for if_ndis is "w22n51.sys" from intel.
The panic was reproducible in single user mode.
>Description:
Trying to use the NDISulator panics the system.
wlan is statically compiled into kernel, ndis module loads fine.
Trying to kldload if_ndis, though, gives a panic:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x80000002
fault code = supervisor read, page not present
instruction pointer = 0x8:0x80000002
stack pointer = 0x10:0xd5483adc
frame pointer = 0x10:0xc20842f0
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 63 (kldload)
The kernel debugger shows only a "kernload()" call in the stacktrace.

>How-To-Repeat:
Install NDISulator as documented, using the Windows driver called "w22n51.sys".
Load if_ndis to panic.
>Fix:
Unknown to me.
