Bug #2280: starting X reboots the machine

Author: Pierre Abbat
Status: New
Priority: Normal
Target version: 

I built kernel and world from sources downloaded this morning with Git. I rebooted and, while attempting to start kdm, the box said "F1: DragonFly" and rebooted. I rebooted the previous kernel and X came up fine. I also tried startx on the new kernel without kdm; it still rebooted.
