Workstation 23 (Beta) locking up

Tue Oct 6 02:38:55 UTC 2015

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.
