Ron, could you please test the latest upstream kernel available (not the daily folder, but the one all the way at the bottom) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. 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-v3.12-rc7

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:
  iostat: Cannot open /proc/stat: Cannot allocate memory

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I receive an intermittent error using iostat -k 5 : "Cannot open
  /proc/stat: Cannot allocate memory"

  This can also be simply reproduced by entering: "cat /proc/stat", one
  to several (~5-10) times.

  strace on the "cat /proc/stat" method:

  This only seems to happens on specific hardware: Intel Server System P4000CP / S2600CP Motherboard, booted with kernel option: "pci=conf1"

  This does NOT happen on very similar hardware: Intel Server R2312GZ /
  S2600GZ Motherboard

  
  Is there a possible memory, or kernel memory sysctl configurable I'm missing here?
