Hi,

for a while, the X server (pkgsrc) has been dying quickly on a netbsd-9HP Elitebook 2170p with i915 graphics - typically after typing two orthree letters into the xdm username field, although just starting Xorgfails in the same way. This used to work...


The kernel has some related complaints during boot:

I have attached the Xorg.log.

The stack trace appears to point to the intel driver:

Does this speak to anybody?
