Public bug reported:
I'm not quite sure where to file this bug, but I've noticed that the
phone's time/date reset to what appear to be manufacturer defaults
sometimes while power tests are running This even happens sometimes
after I force ntpdate to set the correct time.
On arale devices, the clock resets to 2010-01-01. On krillin devices,
it resets to 2014-01-01. I don't think the bug is hardware-specific,
but the symptoms are.
I've seen this symptom happen...
- 3 times post-test on krillin
- 12 times post-test on arale
- 65 times pre-test on arale
- 78 times pre-test on krillin
The tests generally do some setup (get online, install deps, configure
the device, force the correct date via ntpdate), disconnect USB, measure
performance for a while, reconnect, then collect additional logs and
data. Most date-related errors are before the test runs, and are
corrected before proceeding, but it's especially interesting when it
happens during or after the test.
I see these date symptoms mostly during certain tests...
89 power_usage_bt_on_wifi_disconnected
52 power_usage_flight_mode_on
2 power_usage_idle
Notably absent is the power_usage_display_on test, which suggests the
issue probably does not occur when the screen is on with wifi enabled.
It seems to happen during the tests where network access is turned off.
Power test logs are kept here:
http://people.canonical.com/~platform-qa/power-results/?C=M;O=D
Each test set and test run there includes quite a bit of data and logs to help
with debugging.
The specific recent test runs with this symptom are:
