port-i386/46716: Panic after starting Xorg with intel i915 driver
>Synopsis: Kernel panic after starting X11R7 using intel i915 + drm
>Arrival-Date: Tue Jul 17 17:05:00 +0000 2012
>Release: NetBSD 6.0_BETA2
System: NetBSD daemon.corp.trizetto.com 6.0_BETA2 NetBSD 6.0_BETA2 (GENERIC)
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.
Restart X11 multiple times on a core2 box with i915 graphics. Eventually, the
kernel will panic and dump core.
The only workaround I'm aware of is to reboot and start X11 immediately after
the system boots. Then don't cycle X11 afterwards.
