timeout when run "netcfg" or "getprop init.svc.bootanim" after android booted up

[Yongqin Liu]

There are pretty some cases that it is timed out when run "netcfg" or "getprop init.svc.bootanim" command after android booted up and displayed the console prompt.

From the log and by logging into the board's conmux connection, I found that the timeout seems caused by the suspend function.
So will try make disable_suspend the first thing after android booted up, and see if this can decrease the timeout rate.

And another reason seems to the wrong usage of pexpect.TIMEOUT.
Below is the related talk with mwhudson:

<liuyq> mwhudson, in method wait_home_screen, it is now using "self.run(cmd, response=['stopped', pexpect.TIMEOUT], timeout=5)" to catch timeout
<liuyq> mwhudson, but in fact, the "TIMEOUT: Timeout exceeded in read_nonblocking()." is not caught
<liuyq> mwhudson, so I consider how about trying catch TIMEOUT sentence there
<liuyq> mwhudson, not catch the timeout in the response
<liuyq> mwhudson, how do you think about that?
<mwhudson> liuyq: oh heh
<mwhudson> liuyq: that sounds like a bug actually
<mwhudson> liuyq: if you pass pexpect.TIMEOUT in response the code still waits for the prompt
<mwhudson> and that probably won't appear
<mwhudson> so it will raise an exception
<mwhudson> liuyq: can you file a bug on lava-dispatcher about this?
<mwhudson> liuyq: in the mean time, just catch pexpect.TIMEOUT I guess
<liuyq> mwhudson, sorry, why do you say "and that probably won't appear", the prompt “root@linaro” should appear
<mwhudson> liuyq: but it only waits one more second for the root@linaro to appear
<mwhudson> liuyq: if the timeout is 5 seconds and nothing has appeared, the root@linaro _probably_ won't appear in that 1 more second
