There isn't yet a new kernel in *bionic* -proposed to solve this issue,
so I can't test it.
I have verified that building the 4.15.0-42.45 kernel with the patch
(https://patchwork.kernel.org/patch/10382693/) applied fixes wifi for
16+ threaded systems on bionic.

I encountered this iwlwifi failure while testing the Intel 9260 with the
AMD Ryzen 7 2700x (8 core, 16 thread). By bisecting the kernel, I was
able to narrow it down to the same commit. I can also verify that
setting maxcpus=15, fixes wifi (at the cost of performance).
This is a really important
I can reproduce the issue with ethernet failing on the r8169 on resume
from suspend with the current kernel. This is a regression since a
previous kernel on 18.04 since the symptoms occur after installing
updates.
I can also confirm that Kai's kernel seems to fix ethernet after suspend
on at leas
I tested the package on a new system that hadn't gotten the new firmware
installed yet. Bluetooth works after installing the test package.

The underlying problem appears to be the same (identical errors reported), but
the symptoms can be different. The hardware I'm testing doesn't crash
completely. Instead X creates a non-existent DisplayPort monitor with 1024x768
resolution and 0x0 physical size (on hardware without any DisplayP
I can confirm this bug on both Ubuntu 16.04 and 17.04 on Intel Kabylake
i7-7500U with Sunrise Point chipset. The 4.11 kernel you suggested
fixes the problem, so it is fixed upstream. We should try and backport
the fix into at least 16.04 and 17.04.

Initial testing shows that the test kernel resolves the issue as well.
I will continue to test to check for regressions, but I think we have a

So, installing 14.04.4 works fine, but systems with nvme drives don't
boot after installing 14.04.5.
Steps to reproduce:
1) Install Ubuntu 14.04.5 on a system with an nvme drive
2) reboot
3) instead of booting to a graphical environment, there is an initramfs prompt.
Notes:
Tested the proposed kernel with:
* GTX 970M
* GTX 970
* GTX 1080
All three systems boot into unity as expected with the proposed kernel.
Only the GTX 1080 is in low graphics mode (expected because nouveau
doesn't yet support it)
This should be good to go. It's already a confirmed improvement fo
