>Environment:
System: NetBSD daemon.corp.trizetto.com 6.0_BETA2 NetBSD 6.0_BETA2 (GENERIC) i386
Architecture: i386
Machine: i386
>Description:
After leaving a core2duo box with integrated graphics running and compiling pkgsrc packages all night, I attempted to start X11. I had already started it once when the machine first 
booted and it worked fine. Then I came back about 12 hours later and restarted X11. The framebuffer output was corrupted with blinking boxes colors, followed by a reboot about 10 seconds 
later (I assume the delay was for the crash dump to be written). I have core dumps and what not to aid in the diagnosis.

>How-To-Repeat:
Restart X11 multiple times on a core2 box with i915 graphics. Eventually, the kernel will panic and dump core. 

>Fix:
The only workaround I'm aware of is to reboot and start X11 immediately after the system boots. Then don't cycle X11 afterwards.

 They are duplicates. Sorry. I wasn't sure if my send-pr went through. Do
 you want the core files and friends from /var/crash ?
