Kernel Oops after X-Server shutdown

Kernel Oops after X-Server shutdown

[Thomas Koller]

hi,

shutting down the x-server with dri support on a i830M graficcard lets the 
kernel produce an oops and left the screen black.

without dri support there are no problems with i830M graficcards.

Kernel:     	    	2.4.19
KernelPatches: 

DRI Modules http://www.xfree86.org/~alanh/linux-drm-4.2.0-
kernelsource.tar.gz

ACPI-Patches (acpi.sourceforge.net) acpi-20020821-2.4.19

X-Server: Xfree86 4.2.0

Hardware: TravelMate 621LV

Is there a chance to get Xfree 4.2.0 working with DRI on that hardware? 
maybe this is a bug in the kernel.

best regards
thomas

1. Could you try whether 2.4.20-pre5 [1] fixes this (with 2.4.20-pre5 you
   don't need the external DRI Modules)?
2. If this doesn't help please run the Oops message from 2.4.20-pre5
   through ksymoops as described in Documentation/oops-tracing.txt and
   send the output to linux-kernel.

Thanks for help. I tried 2.4.20-pre5 with acpi patch and no it works. The
Problem seems to be solved.
