[Ryan Tandy <1006212@xxxxxxxxxxxxxxxxxx>]

On a DL380 G5 with a P400 array, this seems to be working again with the
lts-raring kernel (3.8.0-32-generic) and newer (e.g. lts-saucy
3.11.0-13-generic from ppa:canonical-kernel-team/ppa). Can anyone else
verify that?

Bug description:
  On a Hewlett-Packard ProLiant DL385 G1 running precise, linux-
  image-3.2.0-24-generic 3.2.0-24.39, when I issue "ctrl slot=0 create
  type=ld drives=2:4" via hpacucli, the command hangs. In dmesg I find
  the following (full dmesg attached).

  ... and so on until I reboot the machine. When the machine is back up
  and I examine the array configuration in hpacucli, the new voume is
  present and marked "OK".

  The problem is also present in kernel-ppa's v3.4-precise:

  pjdc@prat:~$ cat /proc/version
  Linux version 3.4.0-030400-generic (apw@gomeisa) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5.1) ) #201205210521 SMP Mon May 21 09:22:02 UTC 2012

  so I will tag as unfixed upstream.

  I am also marking as "Confirmed", being unable to run apport-collect
  when reproducing on 3.2, since the machine has no network due to bug
  #1005699.
