Description Bug 2008-05-01 08:21:04 UTC
when I ctrl alt backspace within xorg, the image freezes and kb/mouse lock, and I'm forced to reboot with sysrq.

Switching to console still works fine.
When I kill org from console,  the system stays normal, and I can restart xorg fine etc.

git mesa , git xf86-ati (radeon), git 1.5 xorg server branch, using EXA,  "AIGLX"    "1" X700 128MB

Do you have the same problem with XAA?  Also, is the system locked hard, or can you restart X remotely via ssh?  On r5xx chips, I've noticed I get console corruption when I use EXA composite accel.  I haven't tracked down why yet.  The same may be true of r4xx.

I only use composite accell because otherwise the server doesn't start with exa, i prefer all newfashioned stuff disabled. Havent noticed real console distortion. Will try out XAA now.

You mean bug 15780? That's fixed now.

Can you attach a log file from a frozen X server?

Comment 7 Michel Dänzer 2008-05-01 09:48:38 UTC
When you log in remotely, is the X server still alive? Does it hog the CPU? Can you attach gdb to it and get a backtrace?

Does this not happen with another video driver, e.g. vesa?

Paul:

in your log it says

(II) evdev brain: Rescanning devices (1).

this shouldn't show up if you're using server 1.4 or above. you need to install a more recent version of evdev.

Thanks, it was caused by evdev indeed.
