The guys in the datacenter were unable to give me any more information.

What I could find through pcictl was:

001:00:0: Symbios Logic MegaRAID SAS2108 GEN2 (RAID mass storage,
revision 0x04)
003:14:0: Symbios Logic MegaRAID SAS (RAID mass storage)

I *think* but am not sure that I could query mfi0 with FreeBSD's mfiutil
before installing NetBSD. bioctl mfi0 show doesn't work though:

bioctl: Can't locate mfi0 device via /dev/bio

When the server is booting only the mfi1 card is seen doing its thing.
I'd noticed mfi0 being present was strange but didn't think much of it
(mfi1 did work after all), that is until I noticed the panic on shutdown
appeared to be related to the driver.
