RHV stucked at boot screen after "reboot" from SSH

Hi,
I have installed RHV 4.1 on two of my HP ProLiant DL360p Gen9 servers. Whenever I give "reboot" command from any of SSH connection (like from PuTTY or from RHV-Manager[Hosts-->Maintenance-->SSH]), the server is being stuck at boot loading screen, saying something like this..

==========================================================================================

i8042: Can't read CTR while initializing i8042
mce: Unable to init device /dev/mcelog (rc: -5)
systemd[1]: Cannot add dependency dev-rhvh-rhvh\x2d4.1\x2d0.20170522.0+1.device to initrd.target, ignoring: Invalid argument

Both of the servers are throwing the same error. See the attached screenshots for reference. Please help with this.

Thank you.
