So do all boeing and airbus aircraft have reliable indicators that the reverser is indeed the problem?
The reason I asked this question is because the problem-solving you have to do is nightmarish if you don't have any clear cockpit indicators of what is happening. The big trouble is if you or the other guy shuts off the engine and that turns out not to have been what was causing the problem. I suppose that is why the checklists say to return the suspect engine to idle rather than shut it down, as I have seen some people do in incident reports.
Imagine you've just taken off, a little bit beyond V2 maybe, flaps start coming up, then BAM you experience severe yaw or roll and your airspeed starts decreasing. Is a thrust reverser the first thing that comes to your mind? What other possibilities are there that could cause this state? Severe flap asymmetry and/or uncommanded spoiler deployment?
