Currently just very simple message is shown for unhandlable page, e.g. non-LRU page, like: soft_offline: 0x1469f2: unknown non LRU page type 5ffff0000000000 () It is not very helpful for further debug, calling dump_page() could show more useful information. Calling dump_page() in get_any_page() in order to not duplicate the call in a couple of different places. It may be called with pcp disabled and holding memory hotplug lock, it should be not a big deal since hwpoison handler is not called very often.

README
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.
