Alas, still no luck on F27 x64 with latest kernel

Again, have not seen it in kernel  4.16.3-200 and previous ones.

Comment 10 Scott Dowdle 2018-05-15 19:31:00 UTC

I'm having this issue too... on a Dell Optiplex 9010 with a Radeon HD 7570.  I've also been having occasional wild swings in RAM and swap usage.  Stuff will just start swapping to disk when there is plenty of free RAM available usually after starting a KVM VM that gobbles up a bunch of RAM quickly (but still, plenty of free RAM is available).  Doing a "swapoff -a" for a little while will make the system usable again.

Anyway, here's my kernel log related to the bug report:
