well let's be clear here: none of the workarounds suggested in this thread are fixes, nor are they meant to be, they are workarounds only, to allow some functionality until the actual fix arrives.
the actual fix will be a new kernel package release that has the underlying stack corruption bug fixed. that said, it would be great to get an update here from the bug assignee Andrea, or someone on the ubuntu kernel team. we fully realise the bug is in the upstream linux kernel, and has to be fixed there, but an update on how that fix is progressing, or even a pointer to the upstream kernel bug report would be really great thanks. ;) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1945590 Title: Thinkpad E14 Gen2: Kernel panic with trackpad and trackpoint enabled Status in linux package in Ubuntu: Confirmed Status in linux source package in Impish: Confirmed Bug description: 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.
