I have a system with Gigabyte GA-990XA-UD3 mobo, Phenom II X6 and Radeon HD 5750 graphics card, running Kubuntu 11.10, 3.1.2-030102-generic kernel and fglrx from the repositories (not the Catalyst drivers downloaded from ATI).
The system is not completely stable at the KDE level - the desktop crashes from time to time, and both chromium-browser and thunderbird crash frequently, with dmesg output like:
chromium-browser ......
chromium-browse[2565]: segfault at 68e88968 ip 00007f0463be2c08 sp 00007fff2dd58e50 error 4 in libX11.so.6.3.0[7f0463bad000+133000]
Thunderbird ......
Inconsistency detected by ld.so: ../sysdeps/x86_64/dl-machine.h: 466: elf_machine_rela_relative: Assertion `((reloc->r_info) & 0xffffffff) == 8' failed!
I'm not at a level that I understand what this means, but I suspect I have a shared object library problem. In that regard I note that this system has been upgraded over time from 10.04 to 11.04 to 11.10, and at one time it had the ATI Catalyst drivers, which I've hopefully completely removed, as they gave me much heartburn. That said, I've put some other outputs below - debug outputs from chromium-browser and thunderbird, a list of my environment variables, and lastly results of a search for libGL.so, indicating that those libraries are installed multiple times, and the instances are not the same. I suspect the same is true for other libraries.
So my question is ... what can I do to further diagnose and/or fix the problem.
Thanks, Gus
