I was hoping a firmware update would solve the problem, but now it is
significantly worse. The crashes happen so frequently that the machine

Yep, the changes accepted to B/C-unapproved as part of an SRU should be what we
need.
Marking as a Duplicate so that we can test that SRU as well to hopefully
resolve it for all of us.

We have a fix applied for bug 1808389, and if that's the same issue then
it should help when running the 4.18 hwe kernel in bionic. I plan to

At least for me the error stopped showing up since 11th January up to now.
So whatever I did when experimenting/reporting that bug has resolved it.

@paelzer: agreed. I also tried getting later firmwares from Intel's git

Hi Seth,
to answer at least for me - it never worked on my system.
No "degradation on upgrade" at least for me, just never worked.
I'm considering filing a bug with Intel and or Lenovo (for a remote chance to

@Emmanuel: We generally only update firmware in stable releases in

I thought it might be worth to try the other versions of the FW.
So I renamed the files like:
sudo mv /lib/firmware/iwlwifi-8265-36.ucode
/lib/firmware/DONOTLOAD-iwlwifi-8265-36.ucode
Eventually I ended up with:
-rw-r--r-- 1 root root 1811984 Apr 24 2018
/lib/firmware/DONOTLOAD-iwlwifi-8265-22.
I created a PPA for Bionic with the latest firmware (git of today) merged into
the Package version we have in Disco. That can be found at [1].
But even that didn't help - which means even the very latest upstream will not
fix the issue for us auto-magically.

Hi I'm affected as well.
I had hoped that the HWE kernel would somehow magically make things better but
it doesn't.
