From: Bernhard Walle This patch adds the "reset_devices" option (that's used only by one device driver for now) to the recommended list of command line parameters for kdump. Meaning (Documentation/kernel-parameters.txt): reset_devices [KNL] Force drivers to reset the underlying device during initialization.
