Is it possible to track by some way what kernel system, process or thread

No.
I'd like to analyze a system where there is a lot of memory wired but not
accounted for in the output of vmstat -m and vmstat -z. There are no user
processes which would lock memory themselves.
Any pointers?
Have you accounted for the buffer cache?
John and I have occasionally talked about making procstat -v work on the
kernel; conceivably it could also export a wired page count for mappings where
it makes sense. Ideally procstat would drill in a bit and allow you to see
things at least at the granularty of "this page range was allocated to UMA".
