Marc Kleine-Budde <mkl@pengutronix.de> says: During testing I noticed a crash if unloading/loading the gs_usb driver during high CAN bus load. The current version of the candlelight firmware doesn't flush the queues of the received CAN frames during the reset command. This leads to a crash if hardware timestamps are enabled, and an URB from the device is received before the cycle counter/time counter infrastructure has been setup. First clean up then error handling in gs_can_open(). Then, fix the problem by converting the cycle counter/time counter infrastructure from a per-channel to per-device and set it up before submitting RX-URBs to the USB stack.

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.
