Thanks, it narrows it down. I looked through the Intel HW IOMMU code and
haven't found anything obvious that could explain this.

OTOH, looking again at the dmesg with the crash
(dmesg-3.10.0-rc6-00406-g73bc88c) I can't see the HW IOMMU being
enabled. I'd expect "PCI-DMA: Intel(R) Virtualization Technology for
Directed I/O". Instead I see SWIOTLB being enabled there. But if you are
using SWIOTLB I don't understand why igfx_off makes any difference. Also
the workaround in my patch should be already active for SWIOTLB, so that
shouldn't make any difference either. Could you check if you had that
workaround in your test kernel (1625e7e549 - "drm/i915: make compact dma
scatter lists creation work with SWIOTLB backend")?

Title:
  only external screen is working with asus zenbook ux31e [eDP1]

Status in X.org xf86-video-intel:
  Incomplete
Status in “linux” package in Ubuntu:
  Fix Released
Status in “xserver-xorg-video-intel” package in Ubuntu:
  Fix Released

Bug description:
  This is regression after some recent (2-3 weeks) xorg? update.

  I also tested newest kernel v3.3.0-rc6 with no changes, so we can
  exclude kernel.

  This ultrabook is intensively used. So if you need some testing, i can
  do it only on weekends.
