Looks like intel_guc_reset had the ability to sleep under the uncore spinlock since forever but it wasn't detected until the recent changes annotated the wait for register with might_sleep. I have fixed it by removing holding of the uncore spinlock over the call to gen6_hw_domain_reset, since I do not see that is really needed. But there is always a possibility I am missing some nasty detail so please double check.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
