For SD cardreaders it is extremely common not to have a cache. Consequently, the following messages do not point to a real error one could try to fix but rather describe how the disk works: sd 0:0:0:0: [sda] No Caching mode page found sd 0:0:0:0: [sda] Assuming drive cache: write through Print these messages as warnings instead of errors.

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.
