Here's my rig: Athlon 4600+ x2 4 GB DDR400 Biostar K8T890-A9 motherboard Biostar V6202EL16 GeForce 6200 LE PCIE card I installed FreeBSD 6.1-RELEASE 64-bit with Xorg 7.2 RC3 running Gnome. If I load the nv driver, things run OK for a while but inevitably freeze up. My mouse still works but the rest of the desktop is unresponsive. I can ssh from another machine and see that Xorg is eating up 100% of one of my cores. I'm having exactly the same problem that this guy (http://lists.freedesktop.org/archives/xorg/2006-March/013478.html) reported in March. I don't have this problem with the vesa driver. The last time this happened, I connected to Xorg with gdb and got this stack trace: (gdb) bt #0 0x0000000801d37134 in NVSync () from /usr/X11R6/lib/xorg/modules/drivers//nv_drv.so #1 0x00000008035f3008 in XAAGlyphs () from /usr/X11R6/lib/xorg/modules//libxaa.so #2 0x0000000000506fdf in DamageExtensionInit () #3 0x00000000004fd1df in RenderExtensionInit () #4 0x0000000000445e3d in Dispatch () #5 0x000000000042eae5 in main () What else can I do to help debug this problem? Thanks. </BODY> </HTML>
