Description Lubomir Kundrak 2007-09-15 16:05:13 UTC
Description of problem:

When I launch glxinfo against an X server running on an integrated graphics
hardware of the VIA EPIA chip set, X11 server kills itself after an assertion
fail. All relevant the configuration and log files are attached (hopefully).

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


How reproducible:


Steps to Reproduce:
1. run X11 server configured with the attached xorg.conf on problematic hardware
2. run glxinfo
Actual results:

Program received signal SIGABRT, Aborted.

Additional info:

With this configuration the X server crashes on numerous other occasions -- I'll
look at them shortly and either add to this bug or file others. I tried some on
fc6 and they were reproducible also there. I will provide core dumps upon request.

Comment 4 Lubomir Kundrak 2007-09-15 16:35:04 UTC
Running glxgears with the very same configuration seems to lock X11 server in a
loop, not accepting any clients. (nothing appears in log file). The image of the
gears appears on the screen, but they do not move and the whole image is
corrupted with horizontal lines of randomly colored pixels. Would results of
gcov coverage be helpful to find out where the loop happens?

Killing the server afterwards results in a complete lockup of the machine
(doesn't responde on the console, network, ...).

Ping on this. Is there anything I can do to help solve this issue? Did I provide
enough information?

Comment 7 Dave Airlie 2007-10-05 02:20:34 UTC
does turning off AIGLX help this any (I see you have it commented in your

I'll need to find someone with a VIA machine to figure this out it might be
worth trying to report it upstream on bugs.freedesktop.org

Comment 8 Lubomir Kundrak 2007-10-05 08:02:17 UTC
glxinfo doesn't crash the server anymore, glxgears triggered a Segmentation
Fault. I didn't grab the core file this time.

Comment 10 Bug Zapper 2008-04-04 13:50:53 UTC
Based on the date this bug was created, it appears to have been reported
during the development of Fedora 8. In order to refocus our efforts as
a project we are changing the version of this bug to '8'.

If this bug still exists in rawhide, please change the version back to
(If you're unable to change the bug's version, add a comment to the bug
and someone will change it for you.)

Thanks for your help and we apologize for the interruption.

The process we're following is outlined here:

We will be following the process here:
http://fedoraproject.org/wiki/BugZappers/HouseKeeping to ensure this
doesn't happen again.

Comment 12 Bug Zapper 2008-11-26 07:48:19 UTC
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '8'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 8's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 8 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 

Comment 13 Bug Zapper 2009-01-09 07:15:33 UTC
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
