The MegaRAID SAS 8888ELP is still not recognized.
pci3: <PCI bus> on pcib3
pci3: <mass storage, RAID> (vendor 0x1000, dev 0x0060) at device 0.0 irq 11
pciconf -lv :
none17 at pci0:3:0:0: class=0x010400 card=0x10061000 chip=0x00601000 rev=0x04 hdr=0x00
vendor = 'LSI Logic (Was: Symbios Logic, NCR)'
device = 'SAS1078 PCI-X Fusion-MPT SAS'
class = mass storage
subclass = RAID
