Red Hat Bugzilla – Bug 201296
Commenting `Load "dri"' causes a lockup
Last modified: 2007-11-30 17:11:39 EST
Description of problem:
When trying to narrow a different problem, I commented the `Load "dri"'
statement from xorg.conf. With that, X would not start. A white band
appears on the LCD, gradually growing in brightness.
Version-Release number of selected component (if applicable):
Always, on the given hardware
Steps to Reproduce:
1. Comment `Load "dri"' from xorg.conf
2. Start X
Video is not initialized, system lockup.
Normal operation (only slower)
This is Dell Latitude D600, which I got from Havoc. His former desktop
group ought to have more of these.
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon R250 Lf [FireGL
9000] (rev 02)
The driver is "radeon", without the "ati" multiplexor.
The problem happens with any kernel which I tried.
I encountered the problem with xorg-x11-drv-ati-22.214.171.124-1, which is current
for FC-5 at present time. I down-stepped the package. It may have been
there for a long time.
Please attach the Xorg.0.log from the failed startup. I suspect X is actually
starting and just doing violently bad things to the display.

When I collected the above log, all the symptoms were the same as I described,
except that the system DID NOT lock up. So, I logged in over the network,
run ps and found that the X process was not present. Then, I collected the log.
However, there's nothing in the log telling anything about the crash, it
just ends abrubtly. There was no oops or other misbehaviour in the system
So it looks that kernel is unable to restore the text mode once X had control
and crashed. That part may be a kernel problem. But my objective is to have
X which does not exit...

How typical, I attached a wrong file. This one is the correct log.
(Verified by running diff)
Seems working now.
