With bolted hash page table entry, kernel currently only use primary hash group when inserting the hash page table entry. In the rare case where kernel find all the 8 primary hash slot occupied by bolted entries, this can result in hash page table insert failure for bolted entries. Avoid this by using the secondary hash group. This is different from what kernel does for the non-bolted mapping. With non-bolted entries kernel will try secondary before removing an existing entry from hash page table group. With bolted prefer primary hash group and hence try to insert the page table entry by removing a slot from primary before trying the secondary hash group.

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.
