+===== System becomes unresponsive and crashes =====
+==== Akonadi+nepomuk eating all CPU power and memory ====
+You can spot this if you login to a terminal and run ''top''. You'll see processes that contain ''akonadi'' in the name taking over 100% of all cores and memory.
+To solve this problem,
+- Login on terminal or ssh to any machine with your user.
+- cd into your home folder, and run the following:<code bash>
+   rm -rf .local/share/akonadi
+   rm -rf .config/akonadi
+   rm .kde4/share/config/akonadi*
+</code>
+- logout and try to login graphically. Akonadi should not freak out
+anymore.
+==== nfs4 mount problems ====
+Due to incompatibility trough versions on nfs4, if in the logs such an error appears:
+<code io>
+Jun 12 13:57:55 balder automount[3145]: umount_autofs_indirect: ask umount returned busy /nfs
+</code>
+then it seemed more stable to switch to nfs3. This is done in '/etc/nfsmount.conf'. Please ask the administrator for such a fix.
