The "good" one is with the previous patch applied to not read the appearance. My aim was to come up with a method of making its failure non fatal, which might be a better solution rather than remove the call for all devices. However, i traced through the code and got to line 500 of shared/att.c which states that the timeout should be fatal, and immediately disconnects. So, if the timeout is fatal by design, im not sure what a fix would look like.
