[Galaxy A3, A5, A7, A8, A9 Original Android Develop] impasta:
I'm going through with the ejecting then remounting the adopted storage via Settings, since I cannot reliably reproduce the system_server crashes (without issuing a "kill -7" command). I also attached the bugreport zip.

Below are the logs I got while I was reproducing the issue, which may also help:

After pressing "Eject" in the Settings app:
