The BUG happens when the kernel tries to detach a device from the domain, but the device doesn't actually belong to a domain. VFIO likely already avoids this because the bridge and device will both be in the same IOMMU group and therefore attached to the same domain. -- You are receiving this mail because: You are watching the assignee of the bug.
