	Matrox Mill. G400 Dual AGP w/ XFree86 4.2.1

>Description:
	I have a 5.0-CURRENT kernel built with static agp support. Upon starting
	xdm, the mga.ko module is automagically loaded. After the loading of
	mga.ko, if I exeucte a `sysctl -a`, I receive:
	Oct 27 13:34:30 edgemaster kernel: /usr/src/sys/kern/kern_sysctl.c:1000: could sleep with "drm memory" locked from @/dev/drm/drm_memory.h:217
	on the console.
	
>How-To-Repeat:
	1. Build kernel with 'device agp'
	2. Install Xfree86 4.2.1 from portsl
	3. Set up XF86Config like so:
	Section "Module"
	        Load  "dri"
	        Load  "glx"
	        Load  "ddc"
	        Load  "dbe"
	        Load  "extmod"
	EndSection
	4. Start X
	5. Execute `sysctl -a`
	6. Check console and/or syslog.

>Fix:
	Not sure. I haven't gotten a grasp on that part of kernel programming
	yet.
