>Description:
We have 4 MSA60 disk shelf with 14 raid arrays on it (all of them on one 2 port HP E600 controller with daisy-chain). All works perfectly. When we try to add another one MSA60 disk-shelf in daisy-chains BSD have kernel dump during dump with error:
ciss1: adapter claims to report absurd number of logical drives (23 > 15)
kernel trap 12 with interrupts disables

>How-To-Repeat:
Just use more then 15 disk array on one ciss-controller.
>Fix:
