If a block device driver cannot fetch all requests from the blocklayer it's in his responsibility to call the request function at a later time. Normally this would be done after the next irq for the underlying device is handled. However in situations where we have no outstanding request we have to schedule the request function for a later time. This is determined using an internal counter of requests issued to the hardware. In some cases where we give a request back to the block layer unhandled the number of queued requests was not adjusted. Fix this class of failures by adjusting queued_requests in all functions used to give a request back to the block layer.
