dmesg from crash with proposed Ubuntu HWE kernel

The option i915.reset=1 seems to work: with it, there is no system crash after
the GPU hang, at least for now (more than 20 minutes). Setting
intel_iommu=igfx_off and removing the other i915 options had not effect, only
i915.reset=1 worked.

The attached file has dmesg from a system crash with 4.18.0-42, the HWE kernel
for Ubuntu Bionic Beaver.

At least for now, i915.reset=1 seems to solve the system crash.
