The etnaviv devcoredump is created in the GPU reset path, which must make forward progress to avoid stalling memory reclaim on unsignalled dma fences. The currently used __GFP_NORETRY does not prohibit sleeping on direct reclaim, breaking the forward progress guarantee. Switch to GFP_NOWAIT, which allows background reclaim to be triggered, but avoids any stalls waiting for direct reclaim.

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.
