Any reaction yet?
I'm having the same problem: BBU is useless, controller doesn't work with BBU. After removing the BBU controller works perfectly. I'm also using firmware 815E.
I just installed AXXRIBBU01 on a SRCS28X Controller.
As soon as the batterypack is installed the controller won't POST anymore so there is no more Raidcontroller seen by the BIOS.
When I remove the pack it works.
Raidcontroller Bios is 815E .. is this a known problem or just a defective BBU ?
