The day before yesterday I did a system update, including downloading and installing a new kernel (v. 4.4.180-102.1.x86_64). I didn't reboot however; rather I continued to run the previous kernel (4.4.179-99-default). This may be worth mentioning only because towards the end of the day yesterday my system froze up. That is, I could move the mouse pointer around, but clicking on any window did nothing. This meant that I couldn't switch to any other window, so no way to try to diagnose anything. From gkrellm, however, I did see that both RAM and swap usage were normal, not maxed out, so no runaway processses. But the only way to get out of that frozen system was to power down via the power switch. Turning the laptop back on, I booted into the new kernel. However, it wouldn't boot. It hung even before I was able to log in, when the text messages about the boot processes were still rolling up the screen. Here's what I saw: ... [ OK ] Reached target System Iniitialization. Starting Show Plymouth Boot Screen... Starting dracut Initqueue hook... [ 1.761617] wmi: Mapper loaded [ 8.862476] nouveau 0000:01:00.0: DRM: evicting buffers...

[ 8.865333] nouveau 0000:01:00.0: DRM: suspending kernel object trees.. And that's where it hung... for at least fifteen minutes (that's about how long it took me to note by hand all of what I saw onscreen). I had to hard-reboot (again), where I selected the previous (bootable) kernel (4.4.179-99-default). There was no problem booting it and haven't had any problems running it for more than a day-and-a-half.
