Issue description
System won't boot on 5.13 Kernel, Currently "works" on 5.11 with no eGPU. System won't boot on any currently installed kernel with eGPU connected.
On 5.13 Kernel, booting doesn't even reach the encryption password step, and just produces a kernel panic with the below error. On 5.11 Kernel, with the eGPU connected, it always gets past the encryption password step, but doesn't always boot into gnome. Sometimes you only get a flashing underscore (once I was able to ctl,alt-f3 into tty3), sometimes only the monitor connected to the eGPU shows gnome, and internal shows Lenovo logo.
In addition, when no eGPU is connected and in 5.11 kernel, it appears still not to have complete functionality. E.g. internal display brightness keys don't work; HDMI port doesn't work.
Apologies if the issue described are two separate issues. The system and all features mentioned have previously worked fine with and without the eGPU connected on 20.04 LTS. (In hindsight I should never have upgraded lol)
