Hello,

The combination kernel 3.15 (e.g. 3.15.1-1, or the newly-released 3.15.1-2 from the repo kernel:stable) + open-source radeon driver completely freezes the system if the HDMI cable is connected before boot. The only solution is the reset button. This is not new to 3.15: I've completely skipped 3.14 due to the same problem, and I'm still using 3.13.7. 

In 3.15 HDMI at least works if the cable gets connected after the DE has been loaded - which did not happen with 3.14 - but it's not completely stable. Xrandr, for example, freezes the system. Loading a new DE (kde, icewm, xbmc-standalone) or DM (kdm, lighdm) freezes the system.

I don't know where to find the appropriate kernel trace: dmesg only shows the 
current boot log, and what I could obtain from /var/log/messages is at the 
end of this message, but I suspect it does not cover the failure.

This happens when I'm using (for example):

OpenSUSE 13.1 (with many extra repos)
Repository: Kernel:Stable
Name: kernel-desktop
Version: 3.15.1-2.1.g3289da4
Arch: x86_64

01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] 
RV710/M92 [Mobility Radeon HD 4330/4350/4550]

OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD RV710
OpenGL core profile version string: 3.1 (Core Profile) Mesa 10.2.1


It seems that at least arch has already gotten a fix: 
https://bugs.archlinux.org/task/39850

And this is the thread I've opened in the opensuse forums:

The code path looks fairly different from the bug report in arch.  So, it's likely a different bug.  If the problem is still seen in the latest 3.15.x stable kernel, it'd be better to report to upstream.

Let's track the radeon HDMI problem on bug 904932.
