@arighi i completely agree with manolo above and have also stated it before above, this bug has to be considered critical for the installer (all the *buntu installers) because on installer launch you just get a total kernel lockup/crash with no possibility to proceed.
in fact i still don't understand why a total kernel crash with stack corruption on certain hardware is not classed as critical in itself (ie this bug itself should have importance critical). as manolo rightly says, an ugly crash on install attempt means any prospective new user trying any *buntu installer on any hardware with this trackpad will quite likely simply give up on *buntu, which is hardly what *buntu as a whole should want. imho there definitely needs to be new installer iso point releases at some stage before 22.04 once the working kernel is officially released. at the very least all ubuntu flavours need to amend their release/install notes with a new "Known issues" item for "Installer and live session" that details this kernel crash, which should be updated (on fixed kernel release) with the work-around (disable trackpad/trackpoint, install, upgrade kernel, re-enable trackpad/trackpoint) to get the system installed. -- 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 Status in linux source package in Jammy: 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.
