Please submit backports for all stable kernels if you wish to see this in older ones to prevent problems like this from happening. But also, why are you still on 4.19.y? What is wrong with 5.4.y at this point in time? If we dropped support for 4.19.y in January, what would that cause to happen for your systems? thanks, greg k-h
