Default cuse4bsd - link_elf: symbol KPTmap undefined

Hello folks!
I've spent most of the day trying to get a webcam and the motion port working.

I know that I need cuse4bsd and webcamd to use my webcam, but I cannot load the cuse4bsd kernel module as I get the following error if I boot with cuse4bsd_load="YES" and/or kldload cuse4bsd:

Code:
# kldload cuse4bsd
kldload: can't load cuse4bsd: No such file or directory

# dmesg | grep cuse4bsd
KLD file cuse4bsd.ko - could not finalize loading

# dmesg | tail -n 1
link_elf: symbol KPTmap undefined

# ls /boot/modules/cuse4bsd.ko 
/boot/modules/cuse4bsd.ko

# grep cuse4bsd /boot/loader.conf
cuse4bsd_load="YES"

I absolutely have no idea of what to do now. I need help, guys and gals...! The only related information found on Google was people who had the same error but for the nvidia driver port. FYI, the webcam is on a server without X11.

Where can I get that KPTmap symbol!?

Thank you for your time!
Frank

Which version of FreeBSD are you using, and how did you install cuse4bsd?

KPTmap lives in sys/i386/i386/pmap.c (i.e., the kernel) and is not something you need to install.

Hi!

Code:
FreeBSD X 8.0-RELEASE-p4 FreeBSD 8.0-RELEASE-p4 #0: Thu Jul 15 20:16:51 EDT 2010     root@X:/usr/obj/usr/src/sys/GENERIC  i386
I installed cuse4bsd from the latest version located in the ports tree.

Code:
$ find / -name pmap.c
/usr/src/sys/amd64/amd64/pmap.c
/usr/src/sys/arm/arm/pmap.c
/usr/src/sys/i386/i386/pmap.c
/usr/src/sys/i386/xen/pmap.c
/usr/src/sys/ia64/ia64/pmap.c
/usr/src/sys/mips/mips/pmap.c
/usr/src/sys/powerpc/booke/pmap.c
/usr/src/sys/sparc64/sparc64/pmap.c
/usr/src/sys/sun4v/sun4v/pmap.c

$ grep KPTmap /usr/src/sys/i386/i386/pmap.c
$

I don't know how I ended up where I was but after a csup and kernel (8.0 to 8.1), world and userland recompilation, I can now load cuse4bsd.
