[PATCH v2 0/3] Attempt to fixup reset, wedge, unload corner cases

[Matthew Brost <matthew.brost@intel.com>]

We have several bug reports [1], [2], [3] describing failures in reset,
wedge, and unload corner cases where memory is not properly freed or
fences fail to signal. This patch attempts to address the issue by
forcefully killing any remaining queues on driver unload and wedging the
device if not in mode 2.
