For whatever reasons this can happen. For real testcases the test will notice the -EIO and fall over, but we also have some testcases that just read all debugfs files. And that shouldn't cause dmesg spam.
So tune it down a bit so that we still have the information for debugging. And change the errno so that real testcases can easily differentiate.
