Hi,
I recall exepriencing a similar issue with a SuperMicro server and I 
think I worked this around by adding hw.mfi.mrsas_enable="1" to 
/boot/device.hints in order to have FreeBSD booting from the SAS disks.

Unfortunately I do not have access to that hardware anymore (it is 
running AnotherOS and cannot be taken out of production).

I still recommend you do open a bug with the details you have so far, 
having FreeBSD on server with SAS disks is not a sin ;) and software 
causing memory corruption shall be fixed anyways.
