![]() The transport io timeout behavior wasn't quite correct. It ignored that the io error handler is supposed to be synchronous so it possibly allowed the blk request to be restarted while the io associated was still aborting. Timeouts on reserved commands, those used for association create, were never timing out thus they hung out forever. To correct: If an io is times out while a remoteport is not connected, just restart the io timer. The lack of connectivity will simultaneously be resetting the controller, so the reset path will abort and terminate the io. If an io is times out while it was marked for transport abort, just reset the io timer. The abort process is underway and will complete the io. Otherwise, if an io times out, abort the io. If the abort was unsuccessful (unlikely) give up and return not handled. If the abort was successful, as the abort process is underway it will terminate the io, so rather than synchronously waiting, just restart the io timer.
