I'm seeing failures on my i.MX6 boards, both the Q and DL have started
failing in the same way:

# default.time3.0.0.0.PLAYBACK - 44.1kHz stereo large periods
# default.time3.0.0.0.PLAYBACK hw_params.RW_INTERLEAVED.S16_LE.44100.2.16383.131064 sw_params.131064
not ok 10 default.time3.0.0.0.PLAYBACK
# time mismatch: expected 2000ms got 2229

reliably (the actual time drifts by a few ms).  The other boards I've
got coverage of seem fine, and I didn't check any broader CI yet.
