["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Paul Collins, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

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.
