Description Nils Philippsen 2004-10-20 08:41:32 EDT
Description of problem:
On my laptop, upgrading to the latest xorg-x11 (6.8.1-10) causes X to
crash with SIGSEGV. This is regardless of whether I try it with the
included open source "nv" driver or the proprietary "nvidia" one.
Before anyone asks ;-), this problem occurs on a freshly booted,
untainted system, without the proprietary nvidia libraries in the
library path. The problem is there on both kernel-2.6.8-1.610 and

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
- Upgrade to xorg-x11-6.8.1-10
- try to start X (run "X")

Actual results:
X crashes with signal 11

Expected results:
X starts without crashing

Forgot: Downgrading to -8 solved the problem for me.

Comment 9 Kristian Høgsberg 2004-10-20 13:54:53 EDT
Thanks for reporting this.  There should be an xorg-x11-6.8.1-12 out
soon to fix this, in the meantime, avoid the xorg-x11-6.8.1-{9,10,11}
builds and stick to xorg-x11-6.8.1-8.

Status update:

Since many people are encountering this issue and wanting to know
when the fix will be available, I thought I would provide a simple
update to keep everyone in the loop.

The problem was introduced in a patch which first appeared in the
6.8.1-9 build, which will probably cause most if not all systems
to fail regardless of video hardware or driver being used.  Once
the problem was discovered, Kristian updated his patch to fix the
issue in 6.8.1-12 which we've done some local testing with.

The problem is now fixed in internal CVS, and new packages will
be available once they have passed through our buildsystem.  It
may take several hours, or even a day or more before the -12
build is built on all 7 architectures, depending on the load on
the buildsystem and other factors.  The current time estimate
is that a build should be available before next Monday at the
latest, and a few hours at the earliest.

For those who need a fix in the meantime, please use 6.8.1-8
until we have made -12 available.  As soon as the 6.8.1-12
build is available, I will upload it to people.redhat.com and
provide a URL here for people to download the new rpms for

In the mean time, please watch this bug report for status updates.

Thanks for your patience.

xorg-x11-6.8.1-12 is now available for download via ftp,
and http at the following URLs:


Please test these packages, and update the report to indicate
if the SEGV is no longer reproduceable.  If the problem persists
change the status to "ASSIGNED", otherwise set the status to

Thanks for testing.
Comment 14 Jeff Moyer 2004-10-20 18:36:22 EDT
-12 fixes the problem for me.

Comment 15 Mike A. Harris 2004-10-20 20:23:20 EDT
Thanks for the update.  Setting status to "RAWHIDE".
Comment 16 Alex Roman 2004-10-20 22:47:05 EDT
I confirm it... -12 fixes the problem.
Thank you for the updates Mike Harris! :D
Comment 17 Mike A. Harris 2004-10-20 22:57:39 EDT
Actually, Kristian fixed it.  ;o)  But he also broke it, so he
gets credit for both.  ;o)

Comment 18 Thomas Cameron 2004-10-21 00:28:34 EDT
I had the same problem on a dual Xeon 1GHz Dell Precision 620 with an
nVidia GeForce2 GTS card.  The xorg-x11-6.8.1-12 packages fixed it.
