APQ8096 has its VDD APC (Power for quad Kryo applications microprocessors) powered by PM8996 PMIC S9, S10, S11 tri-phase regulators (gang). The bootloader may have configured these regulators with non sustainable default values, leading to sporadic hangs under CPU stress tests (cpufreq-bench). Ideally we should enable voltage scaling along with frequency scaling, but for now just set the regulator gang value to a sane voltage, capable of supporting highest frequencies (turbo).

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.
