Currently, decompression error messages can be very uninformative: [ 0.029853] startup: read error [ 0.040507] startup: -- System halted Improve these messages to make it clear that the error originates from the decompression code. Additionally, on decompression failures, if bootdebug is enabled, dump the message ring buffer before halting. This provides more context for diagnosing startup issues.

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.
