Xorg.0.log
When I turn my HDMI-connected AV unit on or off, Xorg (1.17.4) suddenly
crashes.
This has been observed on xf86-video-ati 7.6.1 and 78fbca0. It worked fine
under 7.5.0 and I have bisected the problem to 2f11dcd, which added hotplugging
for DP 1.2. I don't have any DisplayPort hardware here though, it's all
DVI/HDMI.
This is only affecting Zaphod mode. I have tried with no xorg.conf to give me
xrandr mode and I was unable to reproduce the problem there.
I have attached Xorg.0.log, which includes a backtrace. I have looked up the
addresses in radeon_drv.so and they correspond to the area that was changed.
I'm not sure exactly where the first entry is as I don't have a core dump but I
may obtain one later.
