I can confirm that for my work-provided Dell XPS-15-9570 (running KUbuntu
18.04), kernel 4.15.0-177 results in the following problems:
1. It takes forever (~5 minutes) to boot.
2. The WiFi adapter is unclaimed, and no WiFi networks are available.
3. I am unable to manually claim the WiFi adapter (via modprobe, etc.)
In short, 4.15.0-177 is unusable. I had to revert to 4.15.0-176.
Further, today I tried to update to 4.15.0-187, hoping that this problem
had been fixed. Unfortunately, it hasn't been. Kernel 4.15.0-187 is
also completely unusable for me.
I can provide logfiles, etc. if that would be helpful for anyone. --jwc

Title:
kernel 4.15.0.177 break everything on Dell XPS 15 9570
Status in linux package in Ubuntu:
Confirmed
Bug description:
There are many issues including:
- wireless card DISBLED / UNCLAIMED
- no sound output device listed
- strange electrical noise in the speakers when the cpu is under load
- mounting /boot/efi hangs for 1m30

Rolling back to 4.15.0.176 fixes all the issues.
