Yes, we need the qemu workaround to be removed. I see all required kernel patches are in master-next of bionic. Understand that both of these cannot be timed.. but having qemu changes revert today.. would we get updated kernel and qemu in tomorrows daily build? just wanted to understand what would be time window..
