Comment 46 for bug 1774950

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:
