Same problem, with the keyboard not working, so that I couldn't do
anything here. I reported the bug against the Linux kernel, because
everything is fine with a 4.18 kernel (which I had fortunately kept,
otherwise I would have to find a rescue CD somewhere...):

FYI, /etc/fstab contains:

/dev/sdb1       /media/mem      auto user,noauto,noatime    0       0

I've also installed a 4.9 kernel from stable, and it doesn't work
either.

Perhaps what makes 4.18 work is that initrd.img-4.18.0-3-amd64 is
old enough.
