Hi, I have an Acer Swift SF314-41 (laptop) with AMD Ryzen 5 3500U, Radeon Vega Mobile Gfx and 8 GB DDR4 Ram. I tried to install Ubuntu 20.04.3 LTS, Ubuntu 21.10, Kubuntu 21.10, Zorin OS 16 Core and with all of them when I boot I get this error: VGACON disables amdgpu kernel modesetting. I then tried to install Ubuntu 18.04 LTS and it boots fine but after some time (20/30 seconds) it freezes and I can't use keyboard and mouse, i've also tried with external peripherals, same result. But at least it boots so I think it's related to this post. I tried to disable trackpad and trackpoint from the BIOS to confirm my problem but there is no option. I also tried to add commands like "amdgpu.dc=0" inside Grub but i'm not sure that i've placed them in the right place. Do you know if there is any way to install Ubuntu 20.04.3 LTS with an older kernel? I'm a beginner so I might need a detailed guide, thanks. :)

[Test case] Simply boot the kernel on one of the affected systems (e.g., Thinkpad E14 Gen2). [Fix] Prevent the stack out of bound access by applying the following upstream commit (from linux-next): 1d72d9f960cc ("Input: elantech - fix stack out of bound access in elantech_change_report_id()") [Regression potential] The fix is touching the elantech driver, so we could only see regressions with this specific trackpad/mouse driver. [Original bug report] I installed the Ubuntu 21.10 beta and as soon as I boot I get the kernel panic that I am attaching. I also installed Ubuntu 21.04 and upgraded, as soon as I boot with the 5.13 kernel I get the same problem, disabling the trackpad and trackpoint in the bios the problem disappears. Everything works with the 5.11 kernel. I remain available for further details and sorry for my lack of experience.
