ok, thanks, I resolve the issue.

It happens to me in 4.8 too.

Surprise: the same suggestion applies to 4.8! So, read the logs, describe your setup more completely such as by including a full dmesg.

Re: Executing from crontab only does the job when I logged on.
no virtualization, i386, I already read the manpage of cron, didn't say anithing that apply to this situation. thanks anyway.
