The scripts should be in /usr/local/etc/rc.d If it's the standard xdm install, via /etc/ttys, then just kill the xdm process and it will restart from the tty setting.

Should I not be using atapicam with 8.0? This one is old one. I get it sometimes since 7.0 (perhaps, 6.x affected too) on my desktop and it sometimes repeats with 8.0-BETA2 too (GENERIC kernel). It's some kind of race condition because it does not always hang, but often enough to be annoying. There should be a media in drive to make it happen, blank or written.

livelocks and deadlocks on 8.0BETA2
I have a quad-core system that I updated to 8.0 about 2 weeks ago. It ran fine until yesterday when I used the PATA/ATAPI DVD drive to read a disk. Then the fun began. I saw two totally different presentations, but I hope that they both are manifestations of the same problem. First, the livelock. When attempting to play video off of the disk (xine or mplayer) while the CPU was busy, xorg would lock up solid. All CPUs were running a threaded code that run them all at 100%, but they were running niced to 10. Couldn't kill xorg, even with a 'kill -9'. Ate 100% of a CPU, though the CPU it was running on changed periodically. Could not switch to vty. The display was frozen and I could do nothing from the console. I could log in from another system and the system behaved normally. While I could not free the console, I could and did manage to shut down the system and reboot. This happened repeatedly and within a few seconds of starting the video playing. Now the deadlock. This one is weird in one instance. I had finished with a disk and unmounted it. No problems. Then I ejected the unmounted disk. (Yes, df(1) did not show it.) After the disk ejected, the system deadlocked. Frozen completely. Could not even ping it on the net, so it was in the kernel. I had no luck doing anything, so I had to kill power. Then it got worse. The second time this happened, I inserted an erased DVD while the system was in POST. The system started to boot, but, shortly after probing acd0, while the boot was waiting for: usbus7 usbus6 usbus5 usbus4 usbus3 usbus2 usbus1 usbus0, and about the time it should have probed for cd0 (atapicam), the system locked up and would not finish the boot. This is prior to mounting root. After several repeats of this, I ejected the disk from the drive and it booted just fine. Clearly something with ATAPI is not happy. Should I not be using atapicam with 8.0? I won't have access to this system until next Tuesday and the time I have to tinker will be limited, but I can try setting up to break into the debugger (if the system is even seeing the keyboard) or do something else to get an idea of what is going on. -- R.
