Hi Everyone,

Recently I upgraded a machine from 6.8 to 7.2 (Nitrogen). The machine is
randomly frozen and nothing works afterwards. No ctrl+alt+f2,f3,f4 etc.
The machine seems to be reponsive since I can ssh to it.


I've attached the /var/log/Xorg.0.log file


The kernel I am running is: 3.10.0-327.36.2.el7.x86_64

The output of lspci is as follow:
....
01:00.0 VGA compatible controller: NVIDIA Corporation GF116 [GeForce GTX
550 Ti] (rev a1)
...
...

The output of  lsmod | grep nouveau

rpm -qa *nouveau*

I am suspecting that the bug is triggered by the browser
(firefox/chrome)  but not sure though.

Is there a solution / workaround to this?

I've done some research on the net and saw the following links that
describe the problem.
