I don't run Ubuntu 10.04 because I want to. There is a problem with the
futex backport in the -61 kernel that the proposed -62 kernel fixes. As
bug 1327300 makes clear, this is a lucid-specific problem so clearly the
issue will not be present in any newer release. Supported or not,
breaking existing systems and telling users to change releases is a
little... unhelpful.

And you seem to be suggesting that this only affects desktop apps. My
Ubuntu 10.04 SERVER at home would probably disagree with your
assessment, but I'm not stupid enough to run a kernel I know to be
broken on it just to prove a point.

Title:
  Linux 2.6.32-61 futex changes break existing applications

Status in “linux” package in Ubuntu:
  Won't Fix

Bug description:
  I upgraded to this new kernel this morning and after rebooting, 2
  applications failed to work (consistently).

  These apps are:

  google-chrome-stable=27.0.1453.110-r202711 - process runs but no UI is visible
  skype=4.0.0.8-0lucid1 - UI is visible but connection to network never happens

  While originally trying to figure out what was going on I rebooted a
  few times and observed some other issues. Each of these was only
  observed once.

  compiz=1:0.8.4-0ubuntu15.3 failed to start (no window manager)
  USB mouse failed to work
  GDM visual glitches

  I ran strace /opt/google/chrome/chrome and observed that the last
  thing it did was a call to futex.

  Booting the 2.6.32-60 kernel made these programs work. I've updated my
  grub config to boot this kernel by default as a workaround.
