My questions in comment #1 where no answered directly yet, but this still is using only kernel patches so far, I think it is time to add at least a kernel task.
Furthermore it isn't upstream yet and the target being 5.2 is a bit out still, so I'd think you should target 19.10 ** Also affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1782209 Title: KVM SnowRidge Split-lock disable Status in linux package in Ubuntu: Incomplete Status in qemu package in Ubuntu: New Bug description: When bit 29 is set in Test Control MSR register 0x33, a #AC execption is generated for split locked accesses at all CPL irrespective of CR0.AM or EFLAGS.AC.
