@bemotion Thanks, you might be on to something here! I just checked with `boltctl domains` and it lists "bootacl: 0/0", which according to the manpage, means that BootACL is unsupported.
In my uefi settings, ThunderboltBoot, ThunderboltPreBoot, and ThunderboltPorts are already enabled. I just checked the bash_history from my previous notebook (that did never have this issue with the same dock) and found that I once ran something like this: `boltctl enroll <uuid-as-reported-by-boltctl> --policy=auto`. Back then I did this to get the ethernet port to work, which was never an issue on the current machine. On the current machine, the usb keyboard also worked completely fine during boot until October last year, which I don't really understand. So either a new kernel or a firmware update changed the behaviour. Currently, boltctl stated that everything is authorized and enrolled, but the policy is stored as "iommu" instead of "auto". I will also investigate this policy setting further and also reach out to get some help from the Dell support. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2097229 Title: Issues with Thunderbolt in initrd: Devices recognized but not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/2097229/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
