Title:
  LSI SAS 1078 not detected when installing

Status in “linux” package in Ubuntu:
  Incomplete
Status in “linux” package in Fedora:
  Confirmed

Bug description:
  Binary package hint: linux-source-2.6.27

  Trying to install Ubuntu 8.10 on an IBM 3950 M2 with:

  - Chipset ICH7
  - Integrated network card Broadcom NetXtreme II BCM5709 Gigabit Eternet (rev 06)
  - Network card Intel Pro/1000 PT 82571EB (4 ports)
  - LSI Logic/Symbios Logic SAS 1078 PCI-Express Fusion MPT SAS (rev ff)
  - RSA card 

  All devices appear correctly in an lspci command. During the install
  process, only the Broadcom network card is detected, although the
  e1000e driver is loaded. During the disk detection, no disks are
  found, although the mptsas driver is loaded.

  Here you are some information I manually copied from the screen of the
  server (dmesg while detecting the network hardware):

  And here you are part of the result of the lspci command (copied
  manually, too):

  04:00.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1078 PCI-Express Fusion-MPT SAS (rev ff)
  20:00.0 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet Controller (Copper) (rev 06)
  20:00.1 Idem.
  21:00.0 Idem.
  21:00.1 Idem.

  I have been searching the Internet for hours with no luck. I have
  tried disabling the onboard LAN controller with no luck.
