Comment # 8
on bug 73781
from Florent Rougon
Hello,
I am also experiencing this bug on Debian unstable with Linux 3.14 from Debian
experimental and FlightGear 3.0.0. I'll include the corresponding backtrace at
the end of this message.
'lspci -nv' returns the following concerning the graphics adapter (run on
Debian wheezy, but on the same computer of course):

I tested the patch at https://bugs.freedesktop.org/attachment.cgi?id=92645
applied on top of the mesa_10.1.0-5 Debian package. It seemed to be fine with
FlightGear for 2 or 3 hours, until I had a hard lockup: first, the screen went
into power-saving mode as if there were no signal anymore, then it went back
on, but part of the display was garbled (at the bottom IIRC) and the system
appeared to be completely frozen: nothing visible when moving the mouse,
impossible to switch to a virtual console. I had to do a hard reboot, after
which I disabled the patch.
Here follows the backtrace obtained with FlightGear 3.0.0 on Debian unstable,
using Linux 3.14 from Debian experimental, *without the aforementioned mesa
patch*:
