Issues with 12.0 and LSI HBAs

I recently upgraded my home file server from 11.2 to 12.0.  After I did 
so, the BTX loader hangs.

Hardware setup:

Supermicro A1SAi-2750F mainboard (Atom C2750) with 16GB RAM + 128GB SSD 
on SATA3 port

LSI 9300-8i SAS HBA with 8x2TB HDD

The loaded enumerates my 9 devices with BIOS Drive X: diskY and then the 
spinner makes 1-2 revolutions and hangs.  At this point, the system is 
completely non-responsive, even to Ctrl+Alt+Del.  It makes the same 
behavior when booted of the amd64 install media.

I was able to work around this by disabling boot support in the LSI 
firmware, since the 8 drives on that card are part of a data zpool.  The 
OS is on UFS on the SATA3 SSD.  The machine's had no issues with 11.0, 
11.1, or 11.2.

Has anyone seen anything similar, or have a better work around? I am 
running the most recent firmware for both the motherboard and the SAS 
HBA.  I'd like to figure this out before I start updating the assorted 
Opteron/Xeon/etc based systems at work with LSI HBAs from 11.1 to 12.0.
