thank's for your attention but it would not help and of course, first
thing I did was disabling all custom settings, I have no setting which
could influence disk access, it's a desktop ...

other then loading glabel,sem,tmpfs I do not have no any fancy
settings in loader.conf either

please don't start on the machine, it runs fine and is ok

well, for the piece what you asked for:

mount -v
/dev/label/root on / (ufs, local, journaled soft-updates)
devfs on /dev (devfs, local, multilabel)
/dev/label/var on /var (ufs, local, journaled soft-updates)
/dev/label/usr on /usr (ufs, local, journaled soft-updates)
procfs on /proc (procfs, local)
linprocfs on /compat/linux/proc (linprocfs, local)
