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
Created attachment 79818 [details] backtrace [1] - both llvm and mesa with debugging support
Created attachment 79819 [details] backtrace [2] - only mesa with debugging support
(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).
Thanks for the answer. I suspected something like this when saw this in backstrace: #2 0x0000039278c97590 in llvm::llvm_unreachable_internal (msg=0x39278d885ea "Undefined function", file=0x39278d885d5 "AMDGPUISelLowering.h", line=56) at ErrorHandling.cpp:98
