Priority: medium Bug ID: 65016 Assignee: dri-devel@lists.freedesktop.org Summary: [radeonsi] X server segfaults at startup with mesa-9.1* Severity: normal Classification: Unclassified OS: All Reporter: alexander@tsoy.me Hardware: Other Status: NEW Version: 9.1 Component: Drivers/Gallium/radeonsi Product: Mesa
X server segfaults at startup whith mesa 9.1*. No problems with Git snapshots of mesa (these are the only versions of mesa which works on my system). I'll attach two backtraces below:
1. llvm and mesa was compiled with debugging support. Unfortunately this trace is incomplete =/ 2. llvm was compiled without debugging support, mesa was compiled whith debugging support. This trace is complete, but lacks a lot of debugging info.
Hardware:
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Cape Verde PRO [Radeon HD 7750] Subsystem: Giga-byte Technology Device 2260 Kernel driver in use: radeon Kernel modules: radeon
Software: - mesa 9.1.3, also tried earlier minor versions - llvm 3.3_rc2, llvm Git - xorg-server-1.13.4 - xf86-video-ati-7.1.0 - glamor Git - linux 3.8.12

--- Comment #3 from Michel Dänzer michel@daenzer.net --- (In reply to comment #3)
- mesa 9.1.3, also tried earlier minor versions
- llvm 3.3_rc2, llvm Git
The radeonsi driver in Mesa 9.1.y cannot work with LLVM 3.3 or later but requires a snapshot of the git://people.freedesktop.org/~tstellar/llvm master branch (based on LLVM 3.2).
