I'm sorry this was a frustrated triage, I can immagine.

Looking today through the kernel archive, I noticed an answer from
Paolo Bonzini, <62aa6b81-5456-07dc-cf64-e46747d3a70d@redhat.com>,
claiming this is fixed by

https://git.kernel.org/linus/2a266f23550be997d783f27e704b9b40c4010292
which is in 4.15-rc8, and thus confirming that you did not had the
issue anymore in 4.15.

Closing this bug with that version, but do you have a chance to
confirm that?

Regards,
Salvatore
