I am a Linux Mint user, of course which is downstream from Ubuntu. At
the bottom of my post is an "inxi -Fxz" output with my machine info. I
am replying because I am getting issues with exactly the same kernels
(4.15 and up), and 4.14 installed unconventionally via Ukuu seems okay.
My problems that I noticed were:
1) plugged-in HDD (Dell Latitude media bay, SATA bus), no drive
recognized. Reboot with drive plugged in required.
2) wireless settings in Dell BIOS go ignored:
a) wireless switch (WLAN, WWAN, Bluetooth) -this is three checkboxes to
configure each to be controlled by the physical switch on the right side of
laptop.
b) wireless enable (WLAN, WWAN, Bluetooth) -again, three checkboxes, these
enable or disable each.
The resulting behaviors for 2) included physical wireless switch on
right-hand side of laptop being enabled, even though I had it disabled
in BIOS. Also wireless connectivity had dropouts.
The wireless devices I had disabled in the BIOS settings also remained
up and running. This meant that the Bluetooth couldn't effectively be
disabled at BIOS settings.
Different from everyone else's results. These are just the things I
noticed. I have verified this to be related to kernels 4.15 - 4.17.1
(using UKUU), which is why I am replying here.
Below are my "inxi -Fxy" results:

Title:
Suspend fails in Ubuntu and Kubuntu 18.04 but works fine in Ubuntu and
Kubuntu 17.10 (and on Kubuntu 18.04 using kernel 4.14.47)
Status in linux package in Ubuntu:
Confirmed
Bug description:
I have installed Kubuntu 18.04 on 3 different machines (my friend's
and my own) with no suspend problems but my HP Pavilion 11 x360 does
not suspend.
It suspends fine with Ubuntu 17.10, Kubuntu 17.10, Devuan Jesse,
Devuan ASCII and Windows 10 but fails with Ubuntu 18.04 and Kubuntu
18.04.
I have also tried suspend using a live USB of 18.04 on this machine
and it fails in the same way, so does not appear to be caused by any
additional programs that I had installed.
By installing an older kernel (4.14) on Kubuntu 18.04 the suspend
function works as expected.
Running Kubuntu 18.04 with kernels 4.15, 4.16, 4.17 results in the
suspend failure that freezes the machine and requires a hard reset.
Correct behaviour is -
Screen goes blank, fan goes off, power LED flashes to show machine is
in suspend. Pressing power button triggers 'resume' function.
What happens -
Screen goes blank, fan stays on, power LED stays on. Machine stays in
this state and does not respond to any keyboard interaction, mouse
movement or power button presses.
Ctrl + Alt + f1 (or f2, f3, f4 etc) does not get any response.
The only way to use the machine is to shut down by holding down the
power button.
Checking the logs suggests that the machine believes it is in suspend mode
sleep [deep] when it isn't.
Having to hard reset to get any response means that the kernel logs
say no more than sleep [deep]
pm-suspend also results in the same problems with kernels 4.15 and
4.16, but works fine with 4.14.
It is curious that a machine that suspends fine on an earlier 4.14
kernel no longer works with 4.15 and above, whilst 3 other machines
(including one with pretty similar hardware) do not exhibit this
problem.
There are only a handful of questions about it on the forums but at
least 3 other people have the same problem:
https://askubuntu.com/questions/1029405/ubuntu-18-04-crashes-on-
resuming-from-suspend
https://askubuntu.com/questions/1041369/after-upgrading-
from-17-10-ubuntu-18-04-wont-sleep-suspend
I am attempting to round up anyone else with the same issue and point
them to this bug report.
My laptop is HP Pavilion x360 11-n013na
Matalaks is Acer Aspire ES1-511
collisionTwo has XPS 9560
