If there is a flood of faults then the MMU can become saturated while it waits for the kernel to process the first fault and resume it, so that the GMU becomes blocked. This is mainly a problem when the kernel reads the state of the GPU for a devcoredump, because this takes a while. If we timeout waiting for the GMU, check if this has happened and retry after we're finished.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
