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

stevecs, 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>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  Areca ARCMSR Driver hangs under heavy load

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  ARCMSR driver which is included in the linux-image-2.6.24-26-server
  image (version: Driver Version 1.20.00.15 2007/08/30) aborts device
  commands under heavy load (easy method to trigger would be with
  xfs_fsr with a lot of drives (shows up here with large arrays of 60+
  drives)).

  Below is an example (two areca controllers, each has 4 luns/32 drives;
  the controller in this case controlling the second batch of 4 luns
  starts aborting commands and freezes).

  This causes file system corruption and data loss.

  A new driver was produced which can be obtained at:
  ftp://ftp.areca.com.tw/RaidCards/AP_Drivers/Linux/DRIVER/SourceCode/arcmsr.1.20.0X.15-90605.zip

  I have been running this new driver for the past 2-3 days with no
  recurrence, so it's an improvement.  This should be back-ported to the
  kernel to avoid data corruption issues.

  [attached is system heuristic information as well as output of sysrq
  when aborts happen for reference).
