--- Comment From laurent.duf...@fr.ibm.com 2016-10-03 13:01 EDT--- For the record, while trying to recreate bug 146776 using a 4.8.0 kernel in the guest, I faced the issue you mentioned in comment 17 which I was hoping to be fixed with the latest commit in 4.8.0. I'd to mention that the host is running the Ubuntu kernel 4.8.0-17-generic.
