The RS_CTX_ENABLE and CTX_SAVE_INHIBIT bits are not present on ICL anymore, but we still try to set them and then check them with GEM_BUG_ON, resulting in a BUG() call. The bug can be reproduced by igt/drv_selftest/live_hangcheck/others-priority and our CI was able to catch it. It is worth noticing that commit05f0addd9b("drm/i915/icl: Enhanced execution list support") already tried to avoid the save bits on ICL, but only inside populate_lr_context().

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.
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.
