I bought a Thinkpad Thunderbolt 3 Dock Gen 2 for my Thinkpad X1 Extreme. I booted up in Ubuntu 18.04 and it wasn't detecting anything connected so upon reading online it seemed clear that I needed to enable Thunderbolt in bios. I enabled everything in the Thunderbolt dection, with no security. After booting up, the system said "Configuring Thunderbolt Controller... Please do not power off". It stayed like this for 30 minutes and I finally decided to attempt power off but it would not respond. Holding the power button for as long as 60 seconds does nothing. I tried closing laptop lid... I tried unplugging thunderbolt... nothing works.
