Public bug reported:
I've upgraded to 18.04. Since then, it's impossible to use thumb-drives.
If I try, on the first write operation, that operation hangs. Trying to
issue a 'sync' command that hangs too. After a while (some minutes or
so?) I see the following in kernel log / dmesg (see later). It's not
even possible to cleanly shut the computer down, as it also hangs then.
kernel is:
