Input: ALPS - set DualPoint flag for 74 0
I'm a user of the linux-image-generic-hwe-16.04 package on Ubuntu 16.04.
Until last weekend, I've never had this issue (using kernel 4.8.x) but
today on 4.10.0-27-generic this happened twice to me!
If there's a fix for this issue then it should be merged into this
release pretty quick...

I have exactly the same problem with linux-image-4.10.0-27-generic
(4.10.0-27.30~16.04.2) which was installed recently into Ubuntu 16.04
via linux-image-generic-hwe-16.04.
The problem only occurs after suspend and can be reproduced. With the
previous 4.8.0 kernel this did not occur.

@chihchun Actually I could not install your kernel on 16.04 without
breaking dependencies. It requires binutils >= 2.29 (or 2.28, not sure
if I remember correctly) but Ubuntu 16.04 only includes version 2.26. So
I manually edited the config file in your archive to remove that
restriction. I guess o
@chihchun Many thanks for your work on this issue!

@kleber-souza It seems like the issue affects both Zesty and Xenial
(when using the HWE stack). Does that mean that we need an additional
tag "verification-done-xenial" or is it sufficient the way you write it
above? Thanks for clarifying!

there is definitely a bug in the fact that grub-probe is still just
looking for /dev/[device-id] instead of /dev/disk/by-id/[device-id]
which breaks everything every time you have a kernel update unless you
make those symlinks. this was supposedly fixed but you and I are both
having the issue stil
don't remember any issue with 16.10.
I think we could close this ticket or if you have some test that I could
launch, I am at your disposal.
