A race condition exists where a paused VF's H2G request can be processed and subsequently rejected. This rejection results in a FAST_REQ failure being delivered to the KMD, which then terminates the CT via a dead worker and triggers a GT reset—an undesirable outcome. This workaround mitigates the issue by checking if a VF post-migration recovery is in progress and aborting these adverse actions accordingly. The GuC firmware will address this bug in an upcoming release. Once that version is available and VF migration depends on it, this workaround can be safely removed.

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.
