Comment # 6 on bug 1050256 from Takashi Iwai

OK, thanks.  I think I can see the issue reliably on the local machine.
I just need to boot with smaller memory, e.g. mem=1G boot option, start KDE,
then open Firefox.  That triggers the GPU hang immediately.
It implies an issue in the page handling.

BTW, are you using intel X driver (i.e. xf86-video-intel is installed?)  On a
freshly installed Leap 42.3 system, I didn't have it but the modesetting driver
is used instead.

The problem happens no matter which X driver is used, so it doesn't matter
much, but the devils live always in details, hence I'd like to make sure.

In anyway, it'd be good to know whether this happens on XFCE, too (with or
without copmositor).
