Some sky2 chips fire IRQ after S3, before the driver is fully resumed: [ 686.804877] do_IRQ: 1.37 No irq handler for vector This is likely a platform bug that device isn't fully quiesced during S3. Use MSI-X, maskable MSI or INTx can prevent this issue from happening. Since MSI-X and maskable MSI are not supported by this device, fallback to use INTx on affected platforms.

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.
