Comment 42 for bug 838811

Note that I have already tested to death the exact patch of the above referenced commit. However, I mainly did so with an 11.10 computer. That computer has since been migrated to 12.04 beta for iso and other testing.

One test computer:

doug@s15:~$ uname -a
Linux s15 3.2.0-20-generic #33~lp838811 SMP Thu Mar 29 15:04:04 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
doug@s15:~$ cat /proc/version
Linux version 3.2.0-20-generic (bradf@tangerine) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu3) ) #33~lp838811 SMP Thu Mar 29 15:04:04 UTC 2012

Yes, the backported kernel seems to work as expected with respect to this issue. I'm seeing some load average swings that appear to be more than observed with the 11.10 testing. I'll do a all other things equal type test over about 6 or 8 hours to compare with a previously posted graph.

Another test computer (this is the one used for any previous 12.04 and 3.3 RC tests) (it was just bebuilt from scratch a couple of days ago for ISO testing):

doug@test-smy:~$ uname -a
Linux test-smy 3.2.0-20-generic-pae #33~lp838811 SMP Thu Mar 29 15:05:10 UTC 2012 i686 i686 i386 GNU/Linux
doug@test-smy:~$ cat /proc/version
Linux version 3.2.0-20-generic-pae (bradf@tangerine) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu3) ) #33~lp838811 SMP Thu Mar 29 15:05:10 UTC 2012

I had not installed the compiler on this computer, which I need to compile my test program. I had some dependency troubles for awhile...
Anyway, now I got it all working now and the issue is fixed on this computer with this test kernel.
