Summary: Recompiled kernel crash on KMS loading Product: DRI Version: unspecified Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: critical Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: muziofg@email.it
Created an attachment (id=48405) --> (https://bugs.freedesktop.org/attachment.cgi?id=48405) archive containing .config and dmesg output of my custom kernel
With my custom kernel (config and dmesg attached at this message in a tar.gz archive) I have a problem with radeon DRM module.
When the KMS is loading the system is freezed, the keyboard is dead, the machine doesn't answer at the ping and I can only reset the machine. I haven't any debug information because this crash show a black screen and no file (dmesg, kern.log, messages, ecc) are written.
This problem doesn't happen always, but often so it is also difficult to determine when a change in the configuration in the kernel may have solved the problem
I actually use a linux kernel version 2.6.39 on a debian testing. I compile a personalized kernel from the sources packaged by debian.
The problem seems don't happen with the prebuild kernel (I have tried the package linux-image-2.6.39-2-686-pae) but I'm not sure, simply for now, with this, the machine was started without problem
I never had problems with kernel 2.6.38 using a very similar .config file
The radeon card is a HD6670 PCI Express (chip TURKS)
