Title:
  Areca ARCMSR Driver hangs under heavy load

Status in “linux” package in Ubuntu:
  Invalid

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).
