Mario reports that loading r8152 on his system leads to a: netif_napi_add_weight() called with weight 256 warning getting printed. We don't have any solid data on why such high budget was chosen, and it may cause stalls in processing other softirqs and rt threads. So try to switch back to the default (64) weight. If this slows down someone's system we should investigate which part of stopping starting the NAPI poll in this driver are expensive.

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.
