It isn't specified, like a lot of common raid controllers. But does it need
to? It was supported correctly in 4.9 so why should that support disappear
in 5.3? What was changed in twe it doesn't work anymore in 5.3. As
mentioned, another model 3ware controller still works properly after the
upgrade with the twe driver. And then there's still the question why it does
work in safe mode...

It looks like your controller is supported by the twe(4) driver.

Use man ata to check if the ata(4) driver supports it.
