 XFree86 freezes here too if I enable dri, but works fine without dri...
 
 Preloaded elf module "/boot/kernel/agp.ko" at 0xc082321c.
 agp0: <NVIDIA nForce2 AGP Controller> mem 0xe8000000-0xebffffff at 
 device 0.0 on pci0

 System is an NF7-M motherboard with NForce2 chipset.
 
 It loops while doing an ioctl to /dev/dri/card0
 Here is a small part of ktrace of XFree86:
 
  49609 XFree86  CALL  ioctl(0x7,0x20006444 ,0)
  49609 XFree86  RET   ioctl -1 errno 16 Device busy
  49609 XFree86  CALL  ioctl(0x7,0x20006444 ,0)
  49609 XFree86  RET   ioctl -1 errno 16 Device busy
  49609 XFree86  CALL  ioctl(0x7,0x20006444 ,0)
  49609 XFree86  RET   ioctl -1 errno 16 Device busy
  49609 XFree86  CALL  ioctl(0x7,0x20006444 ,0)
  49609 XFree86  RET   ioctl -1 errno 16 Device busy
 *continues for ever*
 
 sys runs at nearly 100% after starting XFree86 (with dri), the console 
 dies and does never come up again. The kernel is up and userland works, 
 so I could ssh in and do ktrace, etc, and shutdown it 'cleanly'..
 
 Sorry, I don't have a null-modem cable yet..
