MST-related amdgpu crash on Cezanne using Lenovo Dock 40AS
Similar to #3026 (closed) and #2210 (closed), I am seeing a crash somewhere in MST with Lenovo Dock 40AS on a Lenovo ThinkPad P14s Gen 2 (AMD Ryzen 7 Pro 5850U) using Linux 6.5.0-14 from Kubuntu 23.10. The MST device is VMM5322 and has the latest firmware from Lenovo, as does the laptop.
I am running KDE Plasma under Wayland and using a Belkin Thunderbolt cable to connect to the dock itself. The display is a Lenovo ThinkVision P27U-20, and the dock is connected to it via DisplayPort.
The screen is detected by Wayland and appears in my Display Configuration; unlike in #3026 (closed) however, there is no output from the external display and it stays in standby, no matter what resolution is requested on the external display.
From dmesg:
