Hi,
I got a Dell WD19TBS Thunderbolt Dock, and it has been working with Linux for years without issues. However, updating to linux-lts-6.6.29-1 or newer breaks the USB ports on my Dock. Using the latest non-LTS kernel doesn't help, it also breaks the USB ports.
Downgrading the kernel to linux-lts-6.6.28-1 works. This is the last working version.
I opened a thread on the Arch Linux forum https://bbs.archlinux.org/viewtopic.php?id=299604 with some dmesg output. However, it sounds like this is a regression in the Linux kernel, so I'm posting this here as well.
Let me know if you need any more info.
Thanks a lot
Fabian
