Since commit35b5f6b1a8("PHYLIB: Locking fixes for PHY I/O potentially sleeping") phy_start_aneg() function utilizes a mutex to serialize changes to phy state, however the helper function is called in atomic context. The bug can be reproduced by running "ethtool -r" command, the bug is reported if CONFIG_DEBUG_ATOMIC_SLEEP build option is enabled.

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.
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.
