WCPU and CPU climb to about 20%, drop to 0 during disk I/O, then start
Note that this is with SCHED_4BSD. I'd need to recompile a kernel to get
similar information for ULE/PREEMPTION.
fx: goes off and compiles a new kernel and comes back when it's done...
Looks like I spoke too soon. The system is now perfectly stable and usable
The problems I was having with ULE were on 5.3-STABLE. I'm now on 5.4-PRE.
Were there significant changes to the kernel in between?

Straightforward audio connection from the amp's line out to the sound
card's line in. The FFT filtering isn't performed on the fly BTW. I use
audacity to grab the audio and then work on it after it's "in the box".
