--- Comment #8 from Camilo Gonzalez <cagonto1980 at gmail.com> ---
I have got the same problem with my NV4C chipset.

I have been looking for the same bug in Fedora bugzilla, but have not found.

I am using 32-bits KDE Fedora 19 with latest version of nouveau.

There are 2 main ways to reproduce the hang, although it happens randomly:

1.- Trying Firefox startup.
2.- Launching KInfoCenter and clicking on Graphical Information -> OpenGL.

Attempting these 2 actions repeteadly should cause the hang.

There is an other trail: the hang began to happen when I enabled hardware
acceleration (kernel parameter nouveau.noaccel=0).

I provoked the hang while ran the command 'dmesg -T -w -x > ./CGTdmesg.log' on
a Konsole terminal.
I have attached the file CGTdmesg.log for more information.
However, there is no significant logs in it.
Everybody can see that a message was being written when the hang started.

I hope this information to be useful.
