I want to mount CephFS with the kernel driver, but when I execute this command on my admin node

mount -t ceph /mnt/mycephfs

The admin node hangs! and I have to reset my machine.

My OS is Ubuntu 14.04 (trusty) with kernel version is 3.16.0-60 and Ceph v9.2.1

I had the same problem. It resolved itself when I upgraded to Jewel. The release notes state that Jewel (the latest version) is the first release where Ceph FS is declared stable, but you can only have one metadata server.

This is the first release in which CephFS is declared stable! Several features are disabled by default, including snapshots and multiple active MDS servers.
