Comment 29 for bug 1938013

I want to add that I too began having problems on my Lenovo T480 after I installed the 4.15.0-151 kernel. I have gone back to kernel 147 and that solved all the problems. My problems were similar to those reported above: the computer sometimes crashed on boot. When it did manage to boot the mouse was often frozen and other things as well did not function, such as volume control from the keyboard. Programs either did not run or malfunctioned when run. When I tried to shutdown, it would often just hang for an extended period of time and it was necessary to use the power button.
