If we see the seqno stop progressing, we abandon the test for fear that the GPU died following the reset. However, during test teardown we still wait for the GPU to idle before continuing, but we have already confirmed that the GPU is dead. Furthermore, since we are inside a reset test, we have disabled the hangchecker, and so there is no safety net and we wait indefinitely. Detect the stuck GPU and declare it wedged as a state of emergency so we can escape.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
