commit4783b9cb37upstream. A recent change introduced a flag to queue up errors found during boot-time polling. These errors will be processed during late init once the MCE subsystem is fully set up. A number of sysfs updates call mce_restart() which goes through a subset of the CPU init flow. This includes polling MCA banks and logging any errors found. Since the same function is used as boot-time polling, errors will be queued. However, the system is now past late init, so the errors will remain queued until another error is found and the workqueue is triggered. Call mce_schedule_work() at the end of mce_restart() so that queued errors are processed.

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.
