Thanks elguavas! With both the trackpad and trackpoint disabled I can
now boot linux-image-5.13.0-20-generic. I can still move the cursor with
the trackpad and do mouse clicks with the trackpad (not the buttons).
Cold reboot requires exiting bios with the save option as others have
mentioned.

Thinkpad E14 Gen2: Kernel panic with trackpad and trackpoint enabled

I have the same issue. ThinkPad E14 Gen 3 Ryzen 3 5300U. Ubuntu 21.10, I
am using this kernel as workaround: 5.12.19-051219-generic #202107201136
Please fix this! Latest version Manjaro boots up fine!

@randomdave, in case you didn't, i think you have to disable the
trackpoint as well as the trackpad.
some people have reported that just disabling the trackpoint but leaving
the trackpad enabled works, but you lose the trackpad buttons and have
to configure tap-to-click.
for others it only works
I have the same hardware as rudolfharney. Kernel panic still happening
in linux-image-5.13.0-20-generic even after rudulf's suggestion "start
BIOS, exit with SAVE=YES". Also, disabling the trackpad doesn't prevent
the panic.

I ended up disabling the trackpad.

Hm.. it's not trivial to revert that commit, because it depends on other
subsystem changes. I was thinking that we may actually corrupt the stack
because elantech_create_smbus() is using too much stack. How about
allocating that i2c_props array in the heap. See the patch in attach.

Looking at the oops it seems that the stack gets corrupted inside
