Marking this as a duplicate of bug 862106, as I'm seeing the same error message for both these bugs

This is not fixed with the fix to bug 862106.

Looks like device AG860440GIIE0GC is blacklisted, can labs team take a look?

What's the hostname of the bot that has the device AG860440GIIE0GC?

Thanks to bev, she told me the device with serial number AG860440GIIE0GC is attached to build193-b7.  I've rebooted the device and it looks healthy.

Something is still wrong, seeing this on the latest run:
https://logs.chromium.org/v/?s=chrome%2Fbb%2Fchromium.perf%2FAndroid_One_Perf%2F1853%2F%2B%2Frecipes%2Fsteps%2Ftracing_perftests_on_Android_device_Android_One%2F0%2Fstdout

This same device seems to be still busted[1]:

This is still failing. Waiting for a response from the troopers.

#6, 7: note that bugs don't appear in the trooper queue unless they either don't have an owner or they're P0.

This likely needs something analogous to https://chromium-review.googlesource.com/c/catapult/+/1145592. In general, that RO file system issue isn't a trooper issue. It's in other stuff I own, though, so I can address it today.
