Research direction

Start by reviewing the attached MMU crash image and the reported kernel, firmware, board, and display details. Investigate whether attaching a 4K display reproduces the V3D crash; done means identifying the failure cause and validating a kernel fix against that scenario.

Written by the indexing model from the issue text.

Description

As per attached image.

Board has been running relatively ok for a few weeks. Attached a 4K tv earlier & several minutes later, crash.
