JIRA: https://issues.redhat.com/browse/RHEL-3987 Upstream Status: https://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git/ commit db621f13961fb858c2545305b62a569ccf95314e Author: John Ogness <john.ogness@linutronix.de> Date: Thu Dec 14 20:48:23 2023 +0000 panic: Flush kernel log buffer at the end If the kernel crashes in a context where printk() calls always defer printing (such as in NMI or inside a printk_safe section) then the final panic messages will be deferred to irq_work. But if irq_work is not available, the messages will not get printed unless explicitly flushed. The result is that the final "end Kernel panic" banner does not get printed. Add one final flush after the last printk() call to make sure the final panic messages make it out as well.

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.
