Now, this is not apparently very common to CentOS or EL server, but I need to hibernate one of myservers after a batch job daily. Current kernel appears to fail with pm-hibernate now.

$ cat /etc/redhat-release CentOS release 6.8 (Final)

$ uname -a Linux xxxx 2.6.32-642.3.1.el6.x86_64 #1 SMP Tue Jul 12 18:30:56 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

pm-hibernate tries but apparently fails.

OK. Last line says the process causing this is cifsd.

Anything to fix this?
