BUG: warning at lib/kref.c:32/kref_get() on with 0.16.4 on 2.6.18-6-686

I have built the em8300 modules from lenny (0.16.4) on a debian etch
system, linux-2.6.18-6-686 kernel.

when i load the resulting em8300 and adv717x modules i get:

em8300: EM8300 8300 (rev 2) bus: 1, devfn: 72, irq: 11, memory: 0xe6000000.
em8300: mapped-memory at 0xf8e80000
em8300: using MTRR

the 0.16.0 drivers in debian etch work for the most part but there is no
model file in sysfs.
i am going to try again with the default kernel from debian-lenny
(2.6.25) and report back.

Additionally unlike what is reported on
http://dxr3.sourceforge.net/howto.html#detboard this is a Creative Labs
DXR3 but uses the adv717x driver.
