If the link is powered off during suspend, electrical noise may cause errors that are logged via AER. If the AER interrupt is enabled and shares an IRQ with PME, that causes a spurious wakeup during suspend. Disable the AER interrupt during suspend to prevent this. Clear error status before re-enabling IRQ interrupts during resume so we don't get an interrupt for errors that occurred during the suspend/resume process.

README
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.
