USB-C cuts off after update to Ubuntu 22.04

Asked by Seb

While using the laptop (Lenovo Thinkpad X1 Extreme Gen5) the USB-C ports become unresponsive until the machine is rebooted.

In particular I use a Lenovo USB-C Ethernet adapter and an external USB-C SATA SSD to regularly upload large amounts of data.

This was not an issue until I updated the laptop from Ubuntu 20.04 and Kernel 5.15 to Ubuntu 22.04 and Kernel 6.1.

I have since updated to Kernel 6.5 and also installed all available updates including firmware and the issue persists.

I can reproduce the problem by simply reading data from my SSD, the disconnection will happen after an appratently random amount of time (a couple minutes) and interrupt the read operation. When this happens the activity LED on the USB-SATA adapter blinks indefinetely. (The LED should blink only when reading.)

Note that the USB-A ports continue working (also for the same SSD with a different cable) as well as wireless networking.

Please let me know what more information I can provide to help finding a solution.
Thanks for any help!
