Turns out CRC interrupts also fail to wake up i915gm/i945gm from C2+. I suppose this is a generic problem, but for most other interrupts the system will be busy enough already prior to the irq being issued. But CRC interrupts are like vblank interrupts and only fire once per frame, so plenty of time to fall asleep in between them. Apply the same core clock gating trick to CRC interrupts that we use for vblank interrupts.

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.
