** Description changed: I'm facing an issue with Thunderbolt in initrd on a Lenovo Yoga X1 Gen8 in conjunction with the Lenovo Thunderbolt 3 Dock (40AN, Gen 2) when using Ubuntu 24 with Kernel 6.8 and 6.11. Cross-checking the same dock and the same SSD within another Laptop (older HP ProBook 450 G6 with only USB 3.2 support, no Thunderbolt) proofs my suspicion that the hardware works fine but it is some software related issue. Step to Step: When starting the Laptop USB generic drivers are loaded and the Dock is recognized. The dock works flawlessly in pre-boot environments such as UEFI and GRUB with the loaded USB generic driver. As soon as GRUB is attempting to start the selected system and initrd is loaded to prompt the LUKS passphrase, I recognize the USB generic drivers are dropped and the Thunderbolt module is loaded due to onscreen prompts: thunderbolt 1-0:1.1: new retimer found, vendor ... thunderbolt 1-1: new device found, vendor ... thunderbolt 1-1: Lenovo ThinkPad Thunderbolt 3 Dock As soon as the Thunderbolt module is loaded the devices connected to the dock shut off: Monitors turn blank, Keyboard backlights and Mouse status indicator LEDs turn off.
