[opensuse-kernel] Kernel 3.15 + radeon + hdmi = freeze

24 Jun 2014

      Hello,

I'm having trouble to get HDMI to work with kernel 3.15 (3.15.1-1 and the 
newly-released 3.15.1-2 from the repo kernel:stable) and the open-source 
radeon driver. If the HDMI cable is already connected before boot, the system 
completely freezes (sometimes/always due to kernel panic?). 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. But 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. 

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

I'm using:

OpenSUSE 13.1
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:
