Just noticed that 3 seconds is not enough sometimes, i'm trying to update to 10 seconds instead.

If 10 seconds works, i will send V2 to do that.

Thanks Zhijian

Since this test will be scheduled by 0Day to a random host that could have only a few cpus(2-8), enlarge the timeout to avoid a false NG report.
