I actually have tested the v3 and v4 patchsets on linux-next up to 2024711 with no error. I havent't tested v4 on linux- 20240712, yet, because next-20240712 has a deadlock issue: https://lore.kernel.org/all/20240712080414.GA47643@xxxxxxxxxx/ (while sending a mail to this issue, I accidently send the old mail, too) Bert Karwatzki
