vsc_identify_silicon() returns -EINVAL in various places without logging what is going on. And there are several bug reports about mei_vsc_hw_reset() failing with -EINVAL before the "silicon stepping version is %u:%u" message get logged, indicating this is coming from vsc_identify_silicon(): [ 10.949657] intel_vsc intel_vsc: hw_reset failed ret = -22 [ 10.988899] intel_vsc intel_vsc: hw_reset failed ret = -22 [ 11.027140] intel_vsc intel_vsc: hw_reset failed ret = -22 [ 11.027151] intel_vsc intel_vsc: reset: reached maximal consecutive resets: disabling the device [ 11.027155] intel_vsc intel_vsc: reset failed ret = -19 [ 11.027157] intel_vsc intel_vsc: link layer initialization failed. [ 11.027159] intel_vsc intel_vsc: error -ENODEV: init hw failed Add proper error logging to mei_vsc_hw_reset() so that it will be clear why it is failing when it fails.

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.
