<pre>My Linux hangs randomly after I replaced my 2x Nvidia cards (ZaphodHeads,
Xinerama) with Radeon 7870 (Gallium, Glamor).
Desktop hangs, I can move the pointer but clicking doesn't have any effect.
After ~3 second the screen goes blank. Sometimes (10%?) it recovers after ~15
seconds. In most cases it just hangs. Linux is totally dead, doesn't answer to
ping, ssh and even Alt+PrtSc shortcuts.
If it recovers, I see this[1] in the dmesg and this[2] in the Xorg.0.log.
[1]
[ 389.821754] radeon 0000:01:00.0: GPU lockup CP stall for more than 10000msec
[2]
(EE) [mi] EQ overflowing. Additional events will be discarded until existing
events are processed.
I am able to reproduce the bug using Linphone (it doesn't mean it hangs just in
Linphone). I call my mobile. Screen goes blank right after connection is
established (connection = when you hear beeping and you wait for the guy to
answer the phone). Therefore, I can test if the changes you provide resolve the
issue.
Using x86_64 Arch Linux 3.9.6-1-ARCH, radeon and glamor from git, KDE.

Tell me if you need more logs.
I will be happy to test any provided fixes.</pre>
