Hi Salavatore,I have kernel "linux-image-4.19.0-10-amd64/stable,now 4.19.132-1 amd64" installed, so it should already include the mentioned commit, if I understand correctly (I'm a bit confused by the two different version numbers used by Debian). I have also tried the most recent kernel "linux-image-5.6.0-0.bpo.2-amd64/buster-backports 5.6.14-2~bpo10+1 amd64". For both kernels, I see the two kworker processes with high CPU load.
