Upstream thinks the following two kernel patches (currently on drm-
intel-staging) might resolve the issue, however they require testing
before they'll commit to them:
commit e6793fa5504ac5c09a8f22f907c2b5f4543af7d9
Author: Chris Wilson <ch...@chris-wilson.co.uk>

drm/i915: Disable all outputs early, before KMS takeover
If the outputs are active and continuing to access the GATT when we
teardown the PTEs, then there is a potential for us to hang the GPU.
The hang tends to be a PGTBL_ER with either an invalid host access or
an invalid display plane fetch.

drm/i915: Move the irq wait queue initialisation into the ring init
Required so that we don't obliterate the queue if initialising the
rings after the global IRQ handler is installed.
