All;
I'm seeing this notification multiple times a day (from 5 - 30 minutes
apart):
Unexpected system error
The system has encountered a problem and recovered.
Name: kernel-core
Version: 4.4.2.301.fc23.x86_64
Detected: 3 minutes ago
Reported: cannot be reported
The kernel log indicates that hardware errors were detected.
This is most likely not a software problem.
I'm running Fedora 23, KDE Plasma Spin with KDE and Cinnamon installed.
On a Lenove Thinkpad X1 Carbon (3rd Gen)
I wonder if I should be doing something to trap & report?
Have a look at the output of dmesg. It may be apparent there what the
issue is. Most likely it's some bad memory or possibly some errant
firmware--either in the BIOS or a device (e.g. a wifi card or
something).
If it's not that, it could be your power supply starting to have issues.
Wonky power supplies do lots of odd things.

I see lots of these:
[ 8521.141831] mce: [Hardware Error]: Machine check events logged
[ 8521.141834] CPU0: Package temperature above threshold, cpu clock
throttled (total events = 280)

Should I be concerned? Anything I can do?
Well, yeah, it appears you have a CPU fan that's dying, or the heatsink
is very dirty. I'd recommend opening up the box and looking at the fans
(especially the one on the CPU) and verify they're turning at the
correct speed and not binding up. Fans are cheap and they're generally
built cheaply as well. I've had to replace dozens of them over the
years.
I'd also see if you can get a vacuum to clean the interior and a
"can o' air" to blow the cruft out of all the heatsinks. When you do
that, do it from the SIDE of the heatsinks parallel to the fins, not
down on top of them and do it GENTLY or you may force dirt into the
sockets--a "bad thing".
I generally open my boxes and give them a real good cleaning at least
once a year. I replace the fans every two years. Cheap insurance--I had
a CPU cook itself once.
