Bug ID: 85801
Summary: [Mobility Radeon HD 4570] Enabling HDMI monitor fails
with kernel versions 3.17/3.16
Product: DRI
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: DRM/Radeon
Assignee: dri-devel@lists.freedesktop.org
Reporter: CE.Mohammad.AlSaleh@gmail.com

dmesg output with the relevant call trace
With kernel version 3.17.2, when I connect my HDMI monitor, it shows up
correctly in xrandr. But when I try to enable it, Xorg freezes and becomes a
zombie process, and the HDMI monitor stays blank. dmesg hints radeon kernel
code is at fault (attached).
Luckily, the system does not completely freeze. I can still connect to the
system through ssh. So I can provide more information if needed.
I remember having similar issues with 3.16 when I tried it. I'm currently using
3.15.5 which does not suffer from this bug.
