Title:
  cciss: hangs in modprobe, prevents server from booting

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I've upgraded an Ubuntu 10.04 LTS server to 12.04 LTS.  It now fails
  to boot.  More specifically, kernel 3.2.0-77 hangs in the cciss driver
  during initialization.

  The hardware is an HP ProLiant DL385 G2.  The RAID controller is HP
  Smart Array P600:

      lspci -knn -s 06:01
      06:01.0 RAID bus controller [0104]: Hewlett-Packard Company Smart Array P600 [103c:3220]
       Subsystem: Hewlett-Packard Company 3 Gb/s SAS RAID [103c:3225]
       Kernel driver in use: cciss
       Kernel modules: cciss

  I can observe the boot process over serial console (attached: serial-console.log).  You can see the kernel messages about cciss being detected, udev messages about modprobe timing out followed by boot process timeouts and a failure to mount the root filesystem.
  You can also see hung task messages from the kernel (kworker/0:2 and modprobe are both hung inside cciss), and you can see some of my futile attempts to look around in the initramfs.

  I can boot an older kernel (2.6.32-73-server, left over from Ubuntu
  10.04 LTS) just fine.  I'm afraid dmesg and other bits of information
  collected by apport for this bug report will be misleadingly from that
  older kernel.

  ===================== WORKAROUND =====================

  Add 'pci=noioapicreroute' to the kernel command line.
