A bit more details: the test times out when loading the first link (https://developer.nintendo.com/) from the hackernews page (https://news.ycombinator.com).

Manual testing with either sites seemed fine in our experimental build.

Do you have the browser log/crash stack when the test fails?

Here is one instance of failure, has stack trace:
https://chromium-swarm.appspot.com/task?id=325f832a5d486510&refresh=10&show_raw=1

When the test is run locally, the test browser stall after the Nintendo page is rendered.

Note that the stack trace is exactly the same as in Issue 657665 (for Windows), so these are effectively the same issue.

In other words, the change of touch flag in this bug simply exposed the same old telemetry bug in linux.

Here is the stack trace from the log in #3 above:

To debug this, you can add DLOG(WARNING) to get more info about why this is failing on you CL.

Grabbing this because I also have https://bugs.chromium.org/p/chromium/issues/detail?id=657665, but realistically I have no idea when I'm going to get to it.

sunyunjia@: could you please rerun the test on linux ToT. IIRC, this bug happened for our CL that changed the default auto behavior (crrev.com/2467913002). We reverted that behavior later on.

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/20b0d38e48ac6294d88377f1b09fbd54eb7704f4

commit 20b0d38e48ac6294d88377f1b09fbd54eb7704f4
Author: sunyunjia <sunyunjia@chromium.org>
Date: Thu Jan 12 14:39:00 2017

Re-enable hackernews telemetry test on linux.

Previously, we disabled the hackernews telemetry test as we tried to set the
default value of touch-events flag to enabled. Now we've changed the strategy
and reset the default value to auto. And recently, we also passed the test with
the flag set to be enabled. So the hackernews telemetry test no longer needs to
be disabled.
