content_unittests failing (flakey) on Android CFI Nexus 5X

Project Member Reported by wjmaclean@chromium.org, Oct 12

Issue description

Device name: Nexus 5X

The following bot seems to regularly fail the device initial setup for content_unittests:

https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Android%20CFI

+bpastene & jbudorick - FYI, in case you know what's happening.

wjmaclean@ - could you provide an example build?

I found e.g. https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Android%20CFI/3200 from Oct 7 failing with:

NoDevicesError: No devices attached.

The only other build from the last 200 builds with a failing content_unittests is https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Android%20CFI/3245 from Oct 11, same failure. So it's not really that regular.

However, a similar error seems to happen relatively regularly for other tests, e.g.:

https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Android%20CFI/3309
Shard #2 of unit_tests failed with:
NoDevicesError: All devices were blacklisted due to errors

It seems we've scheduled something on a swarming bot with a broken or missing device (which normally shouldn't happen, but occasionally might?)

See my comment at crbug.com/894182#c3 for the problems this bot is having.
