Switched back to the default (called "CFS" I think.)
BMQ has severe issues. When emerging something while I play a game
(either native or through wine-proton,) there's long lag spikes and
freezes. Even worse, there's bugs like the system completely hanging
on shutdown, or "umount" hanging with 100% CPU use by two kernel
threads.
Can you try booting with psi=0 and check if that helps? There's a known
bad interaction with the PSI (Pressure Stall Information) mechanism,
which is active by default in many kernel configs. The latest version
of the BMQ patch makes sure to turn it off, you may not have that version
yet. BMQ (and PDS) works fine and has done so for quite a while.
Will have to rebuild again. Does that work on 6.1 kernels? (I only use
LTS nowadays.)
