PCIe correctable errors are recovered by hardware with no need for software intervention (PCIe r5.0, sec 6.2.2.1). Reduce the log level of correctable errors from KERN_ERR to KERN_WARNING. The bug reports below are for correctable error logging. This doesn't fix the cause of those reports, but it may make the messages less alarming.

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.
