Now, let's talk about today. Since 5 days after have the 6 monitors conf
working, I have random freeses. See the z03 configuration.

Some logs are given here: http://forums.gentoo.org/viewtopic-p-6361675.html

In short, at some time, I feel the mouse moving slowly, and the system getting
loaded. Them I see this appear in system messages:

A few minutes later, Thunderbird (ALWAYS displayed on card PCI:1:5-VGA) get's
killed; then firefox (always on PCI:1:5-DVI) a few minutes later. Then, the
machine freeses: cursor don't move, gkrellm stops moving, music stops.

All windows on card pci:1:5 get killed. Windows on other cards stay alive
(until the freese).

Sometimes, I just get the freese, without any application crash or slowdown.

Just after starting X, I see this in syslog:

I wonder why DRM is loaded ... at the same time as I have Xinerama in my conf.
LIBGL_ALWAYS_SOFTWARE=1 does not help.

I wonder where the issue could be: kernel, X, drm, dri, FB, ucode, X radeon
driver ... 

The only thing I can tell is that ... PCI:1:5 is a video card integrated to
motherboard, and it shares memory with the system (video ram is stolen in the
CPU DDR).

Playing with Surround does not impact on bug. Happen in both cases.

The freese usually happens after 2 to 6 hours of desktop use. After a freese,
and pressing the reset button (aka, not letting the machine switch compleetely
down), the probability of a second/thid freese gets very high (usually 5 to
30mn).

I *never* had any freese before july, before updating to "latest everything"
(kernel, drivers, X), before being able to use all 3 cards together.

I wonder if it could be a hardware issue (the motherboard not happy to use
internal card with two external ones ? capacitor getting aged just *NOW* ?
missplugged RAM ?). I have fans everywhere to cool everything.

Just before a freese occurs, once, I have seen garbage in firefox: some website
using flash/JS/Java to display some menu, at some point, some objects of the
page were replaced by "funny patterns". The external shape was apropriate, but
the visible content of object was garbage (colorfull pixels). Only for 1s
(after i click on a button, and until the page was reloaded); only some
elements, not all of them. The machine frose 2mn later.
