Comment 1 for bug 172511

Ok.
My apology.
I cannot recreate the bug.
The checked it for 3 consecutive times (each time running 2 GLXgears at the same time and each time I had to forcefully restart the system due to complete freezing).
But now I checked it again and I was able to run 6 GLXgears without any problem.

But the system still freezes after long period of idle (screensaver).

Oh well ... back to the drawing board.
