Following a suggestion in

I tested older kernels: seems that PAE was always (or at least back to
karmic 2.6.31) prone to OOM under the sleep test.
Curiously I found that non-PAE kernels of that vintage might also OOM,
maybe depending on
Should a CVE be assigned, seeing how this issue causes a DoS?
And then a USN/DSA should be issued when eventually solved.
Should it be reported to SecurityFocus and obtain a BID?
Could the Status be changed to something better than Expired?
Would some kind soul confirm and explicitly state that

Title:
PAE regression: OOM with just a few sleeps
Status in “linux” package in Ubuntu:
Expired
Bug
Now at Ubuntu VERSION=14.04.1 LTS, Trusty Tahr seems that the
one-and-only x86 kernel offered is with PAE, so I cannot easily
demonstrate the difference between PAE and non-PAE kernels.
With the PAE kernel, my machine produces an OOM crash with the
test command
bash -c 'n=0; while [ $n -lt
Expired? That is weird... how come it did not expire between comments#18
and comments#19, between 16Jan and 6Aug?
Anyway the bug is alive... as anyone could easily test, with a simple
bash -c 'n=0; while [ $n -lt 33000 ]; do sleep 600 ((n=n+1));
((m=n%500)); if [ $m -lt 1 ]; then echo -n $n -
[Expired for linux (Ubuntu) because there has been no activity for 60
days.]
** Changed in: linux (Ubuntu)
Status: Incomplete = Expired

Dear Christopher,
Thanks for the hint about the BIOS.
I updated it, the BIOS version went from 2.2.1 to 2.4.0.
With the new BIOS and running non-PAE kernel:

Dear Christopher,
... test the latest upstream kernel ...
Did not I do that already in

? Is there really a need to re-test? (Yes I know that the kernel now is
different

Paul Szabo, as per

an update is available for your BIOS (2.4.0). If you update to this,
does it change anything?
If not, could you please both specify what happened, and provide the output of
