Arch Linux

Ok, now a bit more precise:

The screen doesn't go black when I plug the monitor being in an X session. That part wasn't precise. Simply plugging it in, nothing happens. But running xrandr to get something onto the htmi monitor causes the freeze. In this case, the laptop screen freezes (but doesn't go black) and nothing happens on the hdmi monitor.

Ok, now some data:

I booted my laptop without the monitor plugged in. Then I ran "sleep 60;systemctl poweroff" and "sleep 30; dmesg > dmesg". After that I ran plugged the hdmi monitor and ran

xrandr --output LVDS --auto --primary --output HDMI-0 --auto --right-of LVDS --output VGA-0 --off

Then, waiting :)

Apparently the system didn't crash, because these command lines worked, I did get a dmesg file and the system shut down.

Here's the end of the dmesg output (the complete dmesg is attached):

Ok, after some more research:

It looks like this is caused by radeon running out of virtual memory. I read that it's likely to be a hardware issue. But it's not in my case, since my laptop runs just fine with linux < 3.10. Looks like a bug in the radeon driver?

I also attached my Xorg.0.log, here's the end of the output

Nothing suspicious there I guess.

I haven't done any configuration limiting the virtual memory.

Is there anything else I could provide?

Can you report this bug upstream at http://bugs.freedesktop.org ?

Yes, please report upstream or it won't be fixed.

In the meantime, try booting with radeon.audio=0

Hi guys, sorry for the delay. I will report it. Just one question: Isn't bugzilla.kernel.org the right bugtracker for this issue?

I'll give radeon.audio=0 a shot.

Amazing :) I didn't put radeon.audio=0 in the kernel line, but removed that entry completely. Now everything works just fine. So thanks a lot for this hint, I never would have expected, that this could be the reason.

AFAIK it should be fixed for kernel 3.11
