Does the system normally lock up when idling or when under heavy load? I find that when under memory pressure (start Android Studio, start an emulator, etc) I could make the system so sluggish that the mouse wouldn't even move and switching to a VT doesn't work...
or doesn't seem so; wait long enough and the mouse pointer will move again but it's faster to just power cycle at that point.
If it's a similar problem, then I wonder... Recent changes in swap behavior? On my non-Fedora work laptop with an older kernel, similar memory pressure has a less adverse effect.

Yes it's an Intel one, and yes I'm using a dock but it's only to get
it charged conveniently and connect to other perks - such as wired
network and input devices - but the dock has no monitor attached.
I've had the lockups happen frequently when travelling; been away for
2 weeks now: that implies no dock at all for many days, and even with
several reboots between the last time it was in the dock (obviously,
because of the issue itself).
Thanks,
Sanne
