Re: Random X lockup

I will try to compile X in debug mode, so I will have more info while debug.
(how I read in http://xorg.freedesktop.org/wiki/Development/Documentation/ServerDebugging)

I have this problem only with a pc in others pc i haven't this problem,
but windows don't crash, so I guess that isn't a bad hardware problem.

On the other hand - if you had this 'freeze' with
with many different kernel versions, and different xorg
versions and different video cards etc etc - then realize

I tried only 1 hardware configuration, trying several software configuration
others people have my problem with different hardware configuration

I have read many forums related to the problem
(such as http://forums.gentoo.org/viewtopic-t-198023-postdays-0-postorder-asc-highlight-lockups-start-0.html)
I have this problem since years such as many others people in the world (reading in internet)

Is there only one thread running?
I guess that if you want to debug this, you'll have to
compile xorg from source - so you can actually see what
it's doing in that function.

On the other hand - if you had this 'freeze' with
with many different kernel versions, and different xorg
versions and different video cards etc etc - then realize
that for MOST people it all works perfectly; therefore
it's a large chance that whatever is constant in your
setup is the problem: your hardware. Or, maybe you didn't
try a different videocard (still hardware), or it's
closed source driver...

After reading your first post I thought: man replace your
hardware already. But if the machine doesn't lock up - just
X - then it could certainly be a software problem, I guess.

I doubt this is related to the kernel however.
