Description Jonatan Cerri 2006-05-16 11:50:15 UTC 
Using supported VGA-Card (ATI Radeon 9250 PCI), which is recognized at boot time, starting Xorg reboots the machine ungracefully, if the dri-module is uncommented in xorg.conf. This is the case in the default xorg configuration file generated with Xorg -configure. Commenting the line 'load "dri"' in the section "Module" of xorg.conf makes the problem go away. The card worked with dri hardware acceleration in a previous FreeBSD/i386 installation on a different mainboard/cpu. The Problem started when changing the mainboard and CPU. Current CPU is Pentium D 805, current Board is Asrock 775Dual-880Pro with VIA PT880Pro Chipset and 1GB DDRII Ram in dualchannel configuration.

Output of dmesg |grep drm:

drm0: <ATI Radeon RV280 9200> port 0xe000-0xe0ff mem 0xd8000000-0xdfffffff,0xff6f0000-0xff6fffff irq 17 at device 9.0 on pci0
info: [drm] Initialized radeon 1.19.0 20050911
drm0: <ATI Radeon RV280 9200> port 0xe000-0xe0ff mem 0xd8000000-0xdfffffff,0xff6f0000-0xff6fffff irq 17 at device 9.0 on pci0
info: [drm] Initialized radeon 1.19.0 20050911

'device agp' was removed from the kernel. the kernel runs with the new scheduler, but the problem persists when running with the old 4BSD scheduler.

Fix: 

Comment line 'load "dri"' in the section "Module" in xorg.conf.
How-To-Repeat: Install 6.1-RELEASE with bundled Xorg. Execute startx using xorg.conf with line 'load "dri"' in the section "Module".

You don't mention what version of X server your running.  I'm running FreeBSD 
7.0-Beta3+ with patches to xorg 7.3.

Suggest updating to something more current, and seeing if that eliminates some 
or all of your problems.

Is this still an issue with currently supported versions of FreeBSD?

The PR is rather old, it lacks debugging information
