Both error-capture and relay-logging mechanism use the GuC log infrastructure. That means the KMD must send a log flush complete notification back to GuC after reading the data out. This call is currently being sent synchronously. However, synchronous H2Gs cause problems when the system is backed up. There is no need for this to be synchronous. The KMD wasn't even looking at the return status from it. So make it asynchronous and then there is no issue about time outs.

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 Restructured Text 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.
