To clarify — the above-mentioned gist is not a workaround against the issue, but a sample snippet to repair my machine after it becomes unusable because of this bug. It's just remounting everything which was unmounted to make the machine usable again. It's (obviously) specific to my system, but it might be helpful for those who want to investigate that issue without having to reboot after each try.
