>Description:
The problem was noticed after a 4.10 to 5.3 upgrade.
I have installed another 5.3 from scratch and recompiled the stock
GENERIC config with IPX support to be sure it was NOT an upgrade problem .
Kernel config is the following:

/sys/i386/conf/IPX

include GENERIC
options IPX

issued the make kernel in the /usr/src after cvsup to 5.3-RELEASE-p2 
after reboot

installed the latest ncplib-1.3.4 from ports

ifconfig xl0 ipx 0x8020001

kldload ncp

ncplist s

I got then:


Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0x0
fault code              = supervisor read, page not present
instruction pointer     = 0x8:0xc062bb7a
stack pointer           = 0x10:0xd0850bb8
frame pointer           = 0x10:0xd0850bb8
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         = 479 (ncplist)
trap number             = 12
panic: page fault

The server on the other side of the network is a Novel Netware 4.11
default install with nds and bindery enabled.
If I do not configure the convinient ipx network on xl0
I got  ncplist s
Can't find any file server
without kernel panic
>How-To-Repeat:
Install 5.3-Release from cd, recompile kernel with IPX support, install ncplib from ports, configure 802.2 frametype on the network interface with proper ipx netnumber (same that the netware 4.11 server has) than issue ncplist s
