crash on login with mounted home drive

[ltcddata]

Been using freebsd since 7.1, and by 7.2 added in a drive for /home/user
which has been fine. However I had to stop for around a year around
10.2, but when I came back on 11.2 suddenly logging in with KDE/Gnome
XFCE would grind the computer to a halt and crash either during login or
within 30 seconds. This does not happen if I boot up using only the root
drive, and use the standard /home/user. Currently Mate is the only
desktop I have which works with a mounted /home/user drive, but does
anyone know what is causing this? 

Cheerz..
