Hello Nils, you are right that system freezes are not a wanted behaviour. But hot-plugging a disk isn't that common in embedded systems (except maybe for USB drives). It's a case that isn't tested that often. So most likely no one noticed that bug. I wouldn't see it critical as long as I don't have a project where I need that (either hobby or funded).
Is this a blocking problem for your project? If not you might want to fill a bug report for this. But I suspect that no one will work on that too fast as long as there is no urgent necessity. Note that if it would have been a FAT bug the situation would have been quite different. FAT bugs are bad for all targets and for quite some funded projects too. So I would have tried to fix that as soon as possible.
