Description Da Fox 2011-03-28 07:55:53 UTC 
Since I upgraded from kernel 2.6.37 to 2.6.38 I am experiencing occasional crashes. My computer just crashed for the third/fourth time in two weeks. When it crashes the screen will turn black, but the mouse-pointer remains visible. The pointer however will not move. ctrl-alt-Fx and ctrl-alt-backspace do not work. SysRq-{s,u,b} however does work. I managed to capture the following backtrace in the syslog:

Comment 1 mrsteven 2011-05-16 15:28:20 UTC 
Looks like this is the same problem that happened to me a few minutes ago. I couldn't get a backtrace (didn't have the magic sysrq keys enabled). My chip is the same and the symptoms are exactly the same. Even the music stopped to play. Compositing (KWin 4.6.2) was enabled at that time and it happened while I was scrolling in Firefox 3.6.17 (an hour or so after returning from hibernate).

I'm using kernel 2.6.38 for nearly two months now (2.6.38.6 for maybe a week) and this was the first time I ran into this issue. Maybe KWin 4.6.2 triggers it, because I just moved from KDE 4.4.5 to 4.6.2 a week ago. But I don't know, as it is hard to reproduce.

I'm using the gallium driver. gentoo-sources-2.6.38-r5 is basically kernel 2.6.38.6 with some patches that are not related to the DRM module, as far as I can see.

In this case there wasn't even a mouse pointer visible, so maybe it's another problem? I'm going to activate the magic sysrq key in the next kernel I build, just to make sure...
Comment 3 mrsteven 2011-07-05 13:37:47 UTC 
Sorry, I forgot to mention a change in Comment #2: I had some problems with dual head and page flipping, so I disabled page flipping in xorg.conf with:

Section "Device"
        Identifier "Radeon"
        Option "EnablePageFlip" "false"
EndSection

Both black screens occurred without an external monitor (i.e. single head, LVDS only), as I usually don't have an external one.
