When trying to add some refcounting in sys/dev/vn.c, I wanted to switch
to using the kernel module for vn, which brought another problem
forward, tried to send-pr it, but unfortunately that doesn't work with
hub being replaced temporarily.Anyway:
on a current machine:
dd if=/dev/zero of=/tmp/vntest bs=1024 count=1440
kldload vn
vnconfig -c vn0 /tmp/vntest
vnconfig -u vn0
kldunload -i SOMENUMBER (found with kldstat)
kldload vn
vnconfig -c vn0 /tmp/vntest
crash, kernelpanic,kabang, kaputt :-(
We tried to trace this back somewhere but failed.
