The sunvnet netdev is connected to the controlling ldom's vswitch for network bridging. However, for higher performance between ldoms, there also is a channel between each client ldom. These connections are represented in the sunvnet driver by a queue for each ldom. The driver uses select_queue to tell the stack which queue to use by tracking the mac addresses on the other end of each port. When a connected ldom shuts down, the driver receives an LDC_EVENT_RESET and the port is removed from the driver, thus a queue with no ldom on the other end will never be selected for Tx. The driver was trying to reinforce the "don't use this queue" notion with netif_tx_stop_queue() and netif_tx_wake_queue(), which really should only be used to signal a Tx queue is full (aka XOFF). This misuse of queue state resulted in NETDEV WATCHDOG messages and lots of unnecessary calls into the driver's tx_timeout handler. Simply removing these takes care of the problem.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
