Ok, if the X server is dumping core... That is a start. If you are
using gdm the core will be in /var/gdm. I'm not sure where it might be
otherwise.
I'm running on a radeon x1650 right now and I'm not seeing this or any
issues really. The i915 that I'm testing on, I have seen these shutdown
issues... I'm not certain of the root cause at this point, as I've been
working on interrupts for several days now. What I have seen seems to
be hit or miss... I can't tell if it is taking an exceedingly long time
for gnome/X to shutdown, or if it is just that this laptop is that
slow...
