[Bug 1320428] [NEW] Firefox 29 fails (system hang) under Linux 3.11.0-24-generic, works under 3.11.0-20-generic

[Bill Turner, wb4alm]

Public bug reported:

Note: attached system information captured under Linux 3.11.0-20-generic.
The actual hang occurs under Linux 3.11.0-24-generic.

I am assuming the actual bug has to do with this particular combination of Kernal and Firefox.
tagged it as kernal, as the same version of firefox works under previous kernal

When the SYSTEM hangs, you lose all control. Only a power-switch reboot will recover.
Hang NEVER occurs under Linux 3.11.0-20-generic and will ALWAYS hang when firefox is started under Linux 3.11.0-24-generic

No differences after reinstalling the -24 system, and/or firefox using
Synaptic Package Manager.

Can assist in debugging, but am not an "expert" in linux.

My system uses an NVIDIA GeForce 8600GTS video card.
   ubuntu-drivers-common 1:0.2.91.4
   xserver-xorg-video-nouveau  1:1.0.10-1ubuntu2

if I boot the system under the recently distributed 3.11.0-24-generic
and then start Firefox 29, (also recently distributed)
my system will lockup, and I will have to use the power button to
reboot.

if I boot the 3.11.0-20-generic kernal, then there is no problem.
hints anyone?
