[Doug Smythies <1413149@xxxxxxxxxxxxxxxxxx>]

I reviewed the Ubuntu kernel team e-mail thread.
I do not understand why the bug patch submitted upstream on November 6th seems to have stalled.
I did observe that there wasn't an "ACK", that I could find.
So I wondered of the patch had been modified or another solution was found.
Is there any way to check the status of upstream patch requests?
(by the way, I asked these same questions on IRC, but it was suggest by apw that this bug report submission was the preferred way to proceed.)

  I'm running 64 bit ubuntu 14.10 on an Asus  N550JK-DB74T laptop.  When
  I startup Ubuntu the system load climbs to 1.00 within a minute, and
  it never goes below 1.00 again, despite my processor being idle.  This
  behavior occurs in all the newer kernels I installed from
  http://kernel.ubuntu.com/~kernel-ppa/mainline/  but when I installed
  the kernel from ubuntu 14.04, as well when I ran the ubuntu 14.04 from
  a usb the load average behaved normally, so the bug must have started
  in either kernel 3.15 or 3.16.

  When I posted this to ubuntu forums, a very helpful person able to
  point me to this bug report: https://bugs.debian.org/cgi-
  bin/bugreport.cgi?bug=765717 and to this  submitted patch
  https://lkml.org/lkml/2014/11/5/905 .  When I applied that patch to
  kernel 3.16 my issue was solved.  However it doesn't seem that this
  patch has been has been merged into the kernel, even though it was
  submitted well in time for the 3.19 merge window.  I was advised to
  file this bug report in the meantime.
