Description of problem: If I attempt to enable desktop effects, the X server immediately crashes and/or exits abruptly (I cannot tell which). When this happens, the kernel spits out the messages: [drm:r300_emit_carefully_checked_packet0] *ERROR* Offset failed range check (reg=4e28 sz=1) [drm:r300_do_cp_cmdbuf] *ERROR* r300_emit_packet0 failed The kernel also spits out this message (but does not crash) if I run glxgears, and glxgears itself reports: libGL warning: 3D driver claims to not support visual 0x4b drmRadeonCmdBuffer: -22 (exiting) A strace of the server is uninformative, with no obvious SIGSEGVs or anything. The death is sufficiently abrupt to not clear the graphics from the screen or reset the graphics mode, leaving the text consoles unusable. However, another server can be started and seems to work normally. Hardware platform: ASUS M2N4-SLI motherboard, Athlon 64 X2 Dual Core Processor 4600+, 2GB RAM, with what lspci -v reports as a ATI Technologies Inc R480 [Radeon X800 GTO (PCIE)] display controller (with a primary and a secondary PCI presence; the primary reports in 'lspci -n' as '05:00.0 0300: 1002:5d4f', the secondary as '05:00.1 0380: 1002:5d6f'). The graphics card is connected via the analog VGA out to a Dell 1907FP LCD panel, in case that makes a difference. The crash/abort happens with both an /etc/X11/xorg.conf created by the Fedora Core 5 installer (this machine was originally FC5 and was then upgraded), and the default X configuration that I get when I start the server without an xorg.conf configuration file. Version-Release number of selected component (if applicable): I am using FC6 x86_64, up to date with the current errata, and thus with: kernel-2.6.18-1.2849.fc6 xorg-x11-drv-ati-6.6.3-1.fc6 mesa-libGL-6.5.1-8.fc6 I have also seen this with the previous version of xorg-x11-drv-ati et al. This machine has *never* had the ATI binary fglrx drivers installed on it, and its kernel is untainted from other stuff. I have tried the current kernel.org 2.6.19-rc6 from the git repository, up to date as of today (which is I believe a HEAD of 66c669baa7d70b8d135da67f36c8dba12cea71b8); it behaves the same way. I have also tried previous kernel.org git kernels, again with the same results. How reproducible: Completely. This happens every time I try to enable desktop effects. Additional info: I have a second M2N4-SLI machine, identical except for using an ATI X300 card ('RV370 5B60 [Radeon X300SE]', PCI ID 1002:5b60 and 1002:5b70), that was previously running Fedora Core 6. During the time that it was running FC6, it did not have this problem; I could enable desktop effects and run glxgears with hardware acceleration and without problems. (That machine is now running FC5, so I cannot test anything on it any more.)
Created attachment 142020 [details] Xorg log file from a crash session
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) 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.
Created attachment 142085 [details] My xorg.conf file
Created attachment 142089 [details] Xorg.0.log without a xorg.conf file (and with a crash) Note that between my initial report and getting this data, the machine was moved from the original LCD to a Mitsubishi CRT; I mention it because it shows up as a difference in this Xorg.0.log. The crash/abort/etc is still the same.
I'm not able to reproduce this in FC7t3. Can you upgrade and verify that this is still an issue?
I'm not willing to upgrade to a test release on a machine I use for real stuff, but when FC7 comes out I'll upgrade and see if I can reproduce the problem there.
Fair enough. Moving back to NEEDINFO until then.
Chris, Fedora 7 has been released. Could you please upgrade and verify that this bug is still reproduceable? Thanks.
Reporter, could you please reply to the previous question? If you won't reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.
No information requested provided, no joy for anybody -- closing this bug as INSUFFICIENT_DATA. Reporter, if you could, please, reopen with additional information.
