===================================================
Then I edit /etc/sysctl.conf with follow commands and the system
don't hang while rebooting
vm.dirty_background_ratio=5
vm.dirty_ratio=10
kernel.panic=3
kernel.hung_task_panic=1
kernel.hung_task_timeout_secs=30
But I don't know if it's an appropriate fix or not.
Thanks
