Description Mark van Rossum 2007-10-06 09:32:19 EDT

Description of problem:
When using the radeon driver, 
Option "AGPFastWrite" "1" in xorg.conf causes a system hang.

Now, Xorg.log explicitly warns against this option. However, the problem is 
that it caused no harm in the driver shipped with F7.
So people might suddenly end up with a non-working system.

(Fixing it can be a bit tricky if xdm/kdm is used. You can do it by booting 
from another device, mounting the f8 partition, and removing xorg.conf).


Version-Release number of selected component (if applicable):
     xorg-x11-drv-ati-6.7.194-3.fc8
Hardware:
     ATI9600 FireGL card

How reproducible:
Everytime.

Thanks for the bug report.  We have reviewed the information you have provided
above, and there is some additional information we require that will be helpful
in our diagnosis of this issue.

Please attach your X server config file (/etc/X11/xorg.conf) and X server log
file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file
attachments using the bugzilla file attachment link below.

Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

Hi,

It runs fine when xorg.conf is absent.

I am sorry, but I don'Å§ understand why I should not close it as NOTABUG -- you
do something against which you are explicitly warned not to do, and when you
remove /etc/X11/xorg.conf entirely it works. Closing as NOTABUG, but if you have
any reason for me, why I should reopen, go ahead and make a comment to this bug.
