ASM hangs during startup nomount RHEL7

Oracle grid 12.1.0.2 on RHEL 7 using NFS

During GI root.sh installation on node 1 I'm getting installation failed because ASM takes too much to start.

Analyzing the problem, I've been able to exclude NFS network related issues because ASM takes long time just for startup nomount.

Using:

Standard configuration using oracle-rdbms-server-12cR1-preinstall

Transparent huge pages disabled on both nodes

Standard huge pages enabled on both nodes

ASM takes about 10 minutes to finish startup nomount.

Using strace:
