https://bugs.freedesktop.org/show_bug.cgi?id=29140 Summary: [rs690] Freeze at Xorg startup when using KMS Product: DRI Version: XOrg CVS Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@xxxxxxxxxxxxxxxxxxxxx ReportedBy: steckdenis@xxxxxxxx Created an attachment (id=37174) --> (https://bugs.freedesktop.org/attachment.cgi?id=37174) Complete dmesg (radeon module loaded just after the last line speaking about a segfault of glxinfo) Hello, I have an ATI Radeon X1270 card (rs690m), with 128 Mio of sideport memory and 256 Mio of shared RAM. This memory configuration caused the bug #27529 . I use the 2.6.35-rc5 kernel (linus-tree), Mesa git (as of the 17th of July 2010, commit 184abe8e26f76a50ede43d503aa6bf129d8d6b76, "llvmpipe: Remove unused variable in lp_test_sincos."), libdrm git (as of the first of July 2010, commit b803918f3f77c62edf22e78cb2095be399753423, "drm mode: Return -errno on drmIoctl() failure") and xf86-video-ati git (as of the 15th of July, commit cdeb1949c820242f05a8897d3ddd0718f204dacf, "kms: don't call cursor helper if using software cursor"). Because of the bug #27529, I used to boot my netbook with the "radeon.modeset=0" param, to avoir screen corruptions. Then, I went to vacations. When I returned back to home, I wanted to try the latest versions of all my favorite softwares, especially the shiny new kernel, containing the fix of #27529. I updated all my software stack to the versions I mentionned in the second paragraph, changed "radeon.modeset=0" to "radeon.modeset=1" and rebooted. The reboot was ok. All my services started up nicely, except KDM. When the X server attempts to start, the screen goes black, with a small text cursor at its top left corner. This cursor doesn't move or blinks. The computer doesn't go farther in the boot sequence, it freezes. I rebooted, using the nomodeset option, and killed KDM (which started fine). I launched a small shell loop that continuously write the dmesg output in a file and launched it. While it was running, I unloaded the radeon module and reloaded it with the "modeset=1" parameter. All went fine, my screen was ok, with my text console on it. Then, I restarted KDM, which attempted to start Xorg. The same bug came again. During the "freeze", I was able to see the activity of my hard disk drive (the dmesg loop contains a sync). It makes me thinking that the computer is not hard frozen, only the graphical part. I cannot go to any virtual console at this point, and I rebooted. I attached my complete dmesg, as captured by my small script. Thanks for resolving this bug, I hope it is the last one I will see before having a nice KMS-enabled netbook, and being able to give a try to Gallium3D, which is needed to a have the very nice Blur effect of KWin on my hardware. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
