Actually testing it is just one part of the issue, and actually the less important one. > Ack > But I think ack for other Arm architecture really important here :-) I have to admit that I really hesitate ifwe should add this - the longer I think about it, the more I tend to say no. I understand that it's a quick workaround for the acute problem that works with some tool chains and on some boards. This makes the "pro" for this patch. On the other hand, the fact remains that we do not understand the exact nature of the problem, as nobody has debugged it to the that level yet. So even when we add this, we cannot be sure if it fixes all problems, on all systems, and with all tool chains - it might happen as well that we run into the same issue again soon, or that there are still issues left somewhere, undetected. If we check in this workaround, the motivation for digging for the real cause will fade away quickly, until it hits us really hard. This makes a big "con" for this patch. I call upon everybody who has some time and resources and who is able to reproduce the problem (so far I was not) to help and dig into this, so we can understand what's going on, and finally fix the cause of the problem, instead of trying to hush it up.
