xorg log with backtrace after crash on logout
I'm using Xorg with radeonhd driver on Gentoo x86_64, using KDM as a display manager. When I logout of an Xfce/KDE session, sometimes all goes well, sometimes Xorg just crashes and switches to an empty text console (blinking cursor only), and sometimes the monitor switches to standby mode.
Sometimes I'm able to switch to a text console (with the monitor in standby or not), login as root and restart Xorg successfully, but sometimes the only way out is using the sysrq keys to sync and shutdown somewhat properly.
Most of the times I'm not getting a useful Xorg log, as it ends with the line "(EE) Backtrace:", with no further info following.
However, I randomly managed to get a stacktrace (see attachment). I compiled the affected libraries with debug symbols, however the trace didn't seem to get resolved properly. Hope it helps anyway?
Tried different combinations of kernel, Xorg, mesa, and radeon driver, none seems to work.
Current combination (Gentoo package versions):
- gentoo-sources-3.17.4
- xorg-server-1.15.0
- xf86-video-ati-7.5.0
- radeon-ucode-20140823
- glamor-0.6.0
- mesa-10.3.5
