ok, pleased to report that i did a forced reinstall of the new kernel
from proposed and it is now working fine on my E15 AMD Gen2. don't know
what went wrong the first time but glad the fix is good.
apologies for the static. don't need anyone to check bios versions
anymore. cheers.

just to be clear, the updated bios shows as: R1AET40W (1.16) in the
bios setup screen.
can someone, who the new kernel works for, please confirm that they are

thanks in advance.

why this kernel does NOT work for me but kernel

just tested the 5.13.0-24.24 kernel from proposed, it does NOT fix the
problem on my ThinkPad E15 AMD Gen 2, this kernel just freezes at the
Lenovo logo like all the other broken kernels.
The 5.13.0-22-generic_5.13.0-22.22+arighi2020+1 kernel still works
flawlessly.
what's going on? i though
well if it is another bogus change to "fix released" why does this keep
happening?
and since it is at least "fix committed" how about an update on what
kernel version the fix is in and when it will be released?
@arighi any update? thanks.

@nemodot it's been said that the fix should be in the next kernel

removing the ones you want.

@arighi i completely agree with manolo above and have also stated it

i can confirm that the kernel linked by randomdave above works
perfectly.
so there is your working kernel, bisect away.
(can also confirm the 5.15 kernel still has the bug, every ubuntu kernel
since 5.11 has the bug, apart from the unofficial one linked by
randomdave 2 replies above.)

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 fixe
@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
you can also just disable the trackpad in the bios settings.
then enable it again when a fixed kernel is available.
bit of a super pita having a laptop with no trackpad though, ;) and for
people running the installer (who would have no reason to know to
disable their trackpad or apply boot params
@arighi hi Andrea, any update on where this is going? is there anything
else we can do to test or provide extra info? even "still investigating"

why does a working non-standard kernel mean it's not urgent? this is
urgent, and for the installer, critical, until a fix is released in the
of
just confirming that that _both_ issues still occur with the latest
kernel updates on 21.04 as of today (2021-10-15).
would be really nice not to have to use either of the two hacks
described above to get this working.
i also added the fn key problem to the bug title to aid in searching.
** Summ
oh, i should mention i tried running the 21.10 installer on the same
machine and (as expected) since no-one would know to disable their
trackpad before trying to install, this bug effectively makes 21.10
uninstallable on this hardware, so for installation purposes i'd call
the bug critical.
