LSI SAS1078 on Intel S5520UR board.

[Pawel Tyll]

Hello list,

I'm having a problem with integrated LSI SAS1078 controller on S5520UR
on FreeBSD 8.0-STABLE #1: Sat May  1 02:06:15 CEST 2010

after kldload mpt:

mpt0 at pci0:13:0:0:       class=0x010000 card=0x35058086 chip=0x00621000 rev=0x04 hdr=0x00
    vendor     = 'LSI Logic (Was: Symbios Logic, NCR)'
    device     = 'PCI-Express Fusion-MPT SAS (LSISAS1078)'
    class      = mass storage
    subclass   = SCSI

mpt0: <LSILogic SAS/SATA Adapter> port 0x1000-0x10ff mem 0xb1940000-0xb1943fff,0xb1900000-0xb193ffff irq 16 at device 0.0 on pci13
mpt0: unable to map registers in PIO mode

# mptutil show adapter
mptutil: mpt_open: No such file or directory

on the other hand, mfi doesn't even attach to this device, and
kldunload mpt crashes the system. Is anyone successfully using this
controller on any version of FreeBSD? Anything else I can do to help
debug and fix this?
