Solved my issue with LSI 8480E without BBU. With "write: BadBBU",

I don't know what "BadBBU" is, but from some Googling it seems to be a
setting that overrides BBU detection, and enables write caching even if
the system believes BBU is broken or missing. If true, this may be
dangerous for data consistency.
