Description Bernhard Rosenkraenzer 2006-08-03 16:18:18 UTC
We've had 2 people reporting that launching any OpenGL application (even 
glxinfo) with xf86-video-ati 6.6.1 (and FWIW xserver 1.1.1) 100% reproducably 
crashes the X server.

An identical build (same binary) works well on other hardware, so the problem 
seems to be triggered by specific hardware combinations.

An upgrade to the xf86-video-ati GIT tree as of 2006/07/19 doesen't change 
anything.

Non-working boxes:
Radeon 9600 [1002:4152, subsystem 174b:0290] w/ VIA AGP bridge
Radeon 9600 [1002:4152, subsystem 174b:0290] w/ VIA AGP bridge
Radeon IGP 330M/340M/350M [1002:4337, subsystem 104d:8175] w/ ATI AGP bridge

Working boxes:
Radeon 9200 PRO [1002:5960, subsystem 174b:7c26] w/ AMD K8 AGP bridge
Radeon 9600 Mobility M10 [1002:4e50, subsystem 1025:0046] w/ AMD K8 AGP bridge
Radeon 9100 IGP [1002:5834, subsystem 807d:8107] w/ ATI 9100 IGP AGP bridge, 
Intel CPU
Radeon [1002:4e51, subsystem 174b:0200] w/ SiS AGP bridge

Crash on ATI Radeon 9600
Comment 3 Michel Dänzer 2006-08-04 04:46:03 UTC
Please try to get a backtrace with gdb, see
http://xorg.freedesktop.org/wiki/DebuggingTheXserver .

Does this also happen with AIGLX disabled?

Also, are there any commonalities between the affected systems, e.g. are they
all SMP or something?
Comment 4 Bernhard Rosenkraenzer 2006-08-05 08:19:23 UTC
We just received an identical bug report from someone using a VIA Unichrome 
chipset; while it has (until now) shown up only with ATI cards, the problem 
might not be in the ATI driver.

(Can't help w/ more debug info until one of the people actually having the 
problem gets back, it happens to work perfectly on all my machines)
Comment 5 Bernhard Rosenkraenzer 2006-08-05 08:23:33 UTC
Output of lspci -v on the VIA box showing the same issue:

I don't think any of the boxes are SMP, the only common thing I can see is 
that all (except one) of the nonworking boxes have a VIA AGP bridge

Marking broken (status null/blank) bugs in xorg with no activity in a long time as fixed. Please reopen if you think it's necessary, but first do a search if a similar bug report is already filed and in a NEW/ASSIGNED state. These bugs do not currently show in most search results as they do not have any status.
