We're seeing the following tests intermittently failing on Android FYI Release (Nexus 9).
- depth_capture_tests

The first failure is in this build
https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Android%20FYI%20Release%20%28Nexus%209%29/9399

But there is not a clear culprit CL. The failure appears to be with the following crash
    // If you hit this DCHECK, your dump provider has a bug.
    // Unregistration of a MemoryDumpProvider is safe only if:
    // - The MDP has specified a sequenced task runner affinity AND the
    //   unregistration happens on the same task runner. So that the MDP cannot
    //   unregister and be in the middle of a OnMemoryDump() at the same time.
    // - The MDP has NOT specified a task runner affinity and its ownership is
    //   transferred via UnregisterAndDeleteDumpProviderSoon().
    // In all the other cases, it is not possible to guarantee that the
    // unregistration will not race with OnMemoryDump() calls.
[FATAL:memory_dump_manager.cc(251)] Check failed: (*mdp_iter)->task_runner && (*mdp_iter)->task_runner->RunsTasksInCurrentSequence(). MemoryDumpProvider "ContextProviderCommandBuffer" attempted to unregister itself in a racy way. Please file a crbug.

Sending to ericrk as a first peak (it may be that I'm mis-reading which test is crashing, so please double-check that -- Android logs are messy).
