In the stall model, invalid transactions were expected to be stalled and aborted by the IOPF handler. However, when killing a test case with a huge amount of data, the accelerator streamline can not stop until all data is consumed even if the page fault handler reports errors. As a result, the kill may take a long time, about 10 seconds with numerous iopf interrupts. So disable stall for quiet_cd in the non-force stall model, since force stall model (STALL_MODEL==0b10) requires CD.S must be 1.

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.
