I had thought maybe flaky hardware was an issue, but then I can't 
understand why it would reliably work okay with a GENERIC kernel, and 
reliably fail with a custom kernel.  Is there something in GENERIC that 
I unknowingly removed that lessens the load on the system?

Is there a "good" way to test my system?  I've run memtest86 on it with 
no problems, and since this is one of my hobby systems, I'm not adverse 
to a test that would wipe my FreeBSD installation.  I was planning on 
wiping and reinstalling for 4.11-RELEASE anyways.
