I managed to trigger an atomisp_css_start() error by pushing my test system towards an OOM situation, this resulted in the following errors: atomisp-isp2 0000:00:03.0: alloc pages err... atomisp-isp2 0000:00:03.0: hmm_bo_alloc_pages failed. atomisp-isp2 0000:00:03.0: stream[0] start error. But it is not entirely clear what the root cause of the "alloc pages err..." error is. I suspect the root cause is alloc_pages_bulk_array() failing. Add a log message to make the root cause more clear if this is hit again.

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.
