>Description:
Kernel panics when the IPX address on a network interface is changed.
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0xdeadc142
fault code = supervisor write, page not present
instruction pointer = 0x8:0xc022f511
stack pointer = 0x10:0xc5fd1bac
frame pointer = 0x10:0xc5fd1bd8
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, IOPL = 0
current process = 477 (ifconfig)
>How-To-Repeat:
Build and boot a kernel with "options IPX". Perform these commands:
ifconfig lnc0 ipx 0
ifconfig lnc0 ipx 1
(substitute lnc0 for another interface as appropriate)
>Fix:
Not known.
