Current panics on connecting disks to a LSI-3108 controller

I have this Supermicro SUPERSERVER®2028TP
Which hold four nodes each with a X10DRT-PT motherboard
and a LSI-3108 SAS controller connecting to 6 disks.

Trying to run the most recent current snapshot on it.
# uname -a
FreeBSD 13.0-CURRENT FreeBSD 13.0-CURRENT #0

I have installed the OS on a SATA flash DOM.
Booting works fine as long as there are no disks connected to LSI-3108 
Booting with SAS disks connected results in a panic.
Attaching a SAS disk to the LSI-3108 controller give a panic as well.

I have posted screenshots of the panic at:

But basically it crashes in
     mfi_tbolt_send_frame() +0x132

So is there anybody out there that can help me with analyzing and fixing 
this panic?
