DiagonalArg, could you please confirm this issue exists with the latest
development release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains,
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-rc5

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:
  Laggy & Finally Completely Frozen 12.04.2 on Large cp or rsync

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have two pairs of raided disks.  I am trying to copy 1/2 T of data
  from one to the other.  First I tried "cp /from /to".  It seemed to
  behave ok, so I left it overnight.  When I came back in the AM, the
  machine was completely frozen.  I had to use the power switch.  Only
  about 150GB had been copied.  I tried again with "nice -n 10 cp ..."
  and the same thing happened.  Then I discovered ionice and shifted to
  rsync.  So I used "ionize -n 7 rsync -cva /from /to".  I also turned
  off the sleep/lock for the display.  Again it seemed to behave ok, so
  I left it while I went for dinner.  Two-three hours later, I found
  that all windows were frozen.  I couldn't use REISUB, the reset switch
  _or_ the power switch.  I had to power off using the switch on the
  power supply.  Rebooting, I found that about 300G had been copied by
  this point.  I am trying for the 4th time now, again using rsync.
  iotop is running.  It regularly freezes between rsync's copying one
  file and the next.  If I try to shift to a window or type at the
  terminal, there is a freeze until the file being copied by rsync is
  finished.  If I keep typing at the terminal (or in the text-box in
  Firefox, as I am now) then things become smooth until I stop for a
  bit.    Then the freezing begins to happen again.  (That's not
  completely true.  Tab completion at the terminal is a disaster.  Cut &
  paste in this window is the same.)  It may be my fantasy, but it seems
  that if I keep using the machine, getting it to respond to
  keyboard/mouse intput, then it doesn't permanently freeze up.  It's
  when I leave to it's own devices for some time that I have a problem.

  The only difference between the last try and the first 3, is that
  after having a look at dmesg, I enabled IOMMU in the BIOS.  Probably
  irrelevant, but I did also notice the "spurious 8259A interrupt: IRQ7"
  message in dmesg that has been reported in bug #75626.

  I haven't changed anyting with the I/O scheduler, which has been
  reported as causing I/O problems in bug# 427210 and #131094.  So, it
  still reads: "noop [deadline] cfq"

  Tyan S3970 with 2 CPU's (8 cores).
  Two pairs of WD drives (500G & 2T)
  TARO add-on storage card (used by the 2T drives)
  Ubuntu 12.04.3 fully updated.  
  Essentially new install (During this process I only added iotop, atop, htop, acpi, m5deep & emacs)
  500G drives are RAID-1; 2T drives are RAID-1 & encrypted.
