Created attachment 386378 [details] Smolt profile, Xorg.0.log, dmesg, messages, and stack trace Description of problem: Xorg crashes on start up, before running plymouth splash. It's a NVA5 chip with KMS, and with nomodeset it also crashes when text mode plymouth splash ends. Version-Release number of selected component (if applicable): xorg-x11-server-Xorg-1.7.4-3.fc12.x86_64 xorg-x11-drv-nouveau-0.0.15-19.20091105gite1c2efd.fc12.x86_64 kernel-2.6.32.4-30.fc12.x86_64 How reproducible: Always. Steps to Reproduce: 1. Boot a 2.6.32 kernel from koji. Actual results: Crash. Screen looks like it's off. Expected results: You know, seeing gdm etc. :) Additional info: Smolt profile, Xorg.0.log, dmesg, messages, and stack trace are attached. With 2.6.31 from updates laptop boots, but crashes randomly several times a day. I don't know if I should file this too (I figured out that it's better to use the newest kernel).

I'd be glad to know if it's a software bug that could be fixed some time later, my video card model issue, or issue with my specific card or machine that's needed to be reported to my vendor's support.
This looks pretty straightforward: Backtrace: 0: /usr/bin/Xorg (xorg_backtrace+0x28) [0x49ea68] 1: /usr/bin/Xorg (0x400000+0x61a89) [0x461a89] 2: /lib64/libpthread.so.0 (0x3063000000+0xf0f0) [0x306300f0f0] 3: /usr/bin/Xorg (xf86InitViewport+0x4b) [0x51e26b] 4: /usr/bin/Xorg (InitOutput+0xb23) [0x470223] 5: /usr/bin/Xorg (0x400000+0x21bfa) [0x421bfa] 6: /lib64/libc.so.6 (__libc_start_main+0xfd) [0x306281eb1d] 7: /usr/bin/Xorg (0x400000+0x21949) [0x421949] Segmentation fault at address 0x24 Fatal server error: Caught signal 11 (Segmentation fault).
