strange dmesg errors with nvidia driver

[Endymion <endy@xxxxxxxxxxxxxxxxx>]

Hey all,

I'm running a 2.6.12.rc5-mm2 custom compiled kernel, with agpgart 
unfortunatly statically built into the kernel.  I am getting the 
following strange dmesg outputs:

Debug: sleeping function called from invalid context at 
include/linux/rwsem.h:66
in_atomic():1, irqs_disabled():0

Anyone have any idea what is going on and what i can do to correct the 
problem?
