(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.
