--- Comment #4 from Chris "SKip" Mac-Stoker ---
.. just created an account and wanted to post a confirmation of this bug, on a
chassis with this controller, the "AAC: Host Adapter Dead -1" did not appear at
all on an Ubuntu 14.04.1 installation (OS installed, not Live USB), but
suddenly showed up after a fresh installation of 16.04 (amd64) on the same
chassis and persists just like the OP says, every 10s. Otherwise the controller
works normally with a RAID5 4-disk array with no noticeable performance
degradation as tested with hdparm -T.
Copying here the relevant lspci -vv stub in case it helps:
