Hi,
Adding the linux-usb list.
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.
Is there any way you can use 'git bisect' to test inbetween kernel versions/commits to find the offending change?
Does the non-lts arch kernel work properly?
thanks,
