[Bug 1226172] Re: iostat: Cannot open /proc/stat: Cannot allocate memory
Ron, did this problem not occur in a release prior to Raring?
As well, in mainline testing, please ensure you are not testing the
daily folder (nightly as you called it), but the one at the bottom of
the list, as outlined in
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1226172/comments/18

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?
