	On Sept 28th, for no reason, my X started to lock up. I'm
using the nv driver on FreeBSD 5.5-STABLE.

	I recompiled the module with debug, and now when I broke this time
I got :

0x284b21d8 in NVSync (pScrn=0x81da000) at nv_xaa.c:303
303         while(READ_GET(pNv) != pNv->dmaPut);
(gdb) bt
#0  0x284b21d8 in NVSync (pScrn=0x81da000) at nv_xaa.c:303
#1  0x295d3085 in XAAPaintWindow ()
   from /usr/local/lib/xorg/modules//libxaa.so
#2  0x0813e4b0 in DamageExtensionInit ()
#3  0x0810d08b in miClearToBackground ()
#4  0x0807e052 in ProcClearToBackground ()
#5  0x081238f1 in XaceHook ()
#6  0x0807be31 in Dispatch ()
#7  0x0806c025 in main ()

	If I attempt to step at line 303 of nv_xaa.c, I get nowhere...

	Any idea how to tell whats happening?

			Thanks, Tuc
