What happens if you set one of these sysctl values to 0? (This disables  
SMP changes from 5.4 to 6.0.)
debug.mpsafevfs: 1
debug.mpsafenet: 1
debug.mpsafevm: 1

And is there a possibility (performance-wise) to build a kernel with  
WITNESS and/or INVARIANTS options compiled in. This will give more info  
about possible locking problems. Your system will run slower. And because  
of this the problem may not occur anymore, but it is worth the try.
