My system is based on an Intel PB965LT main board with a Q6600 quad core CPU and 8 Gbyte of RAM. I am also using the amd64 kernel, where kernel configuration is almost identical to GENERIC, with devices removed that I do not have and the following lines added device drm device radeondrm device sound device snd_hda If I remove the drm and radeondrm devices from the config file and recompile the kernel, the panic does not occur and the corresponding modules can be loaded without a problem. Some "binary searching" of Subversion releases shows that the problem first occurs with r194985. If I update to r195137 and revert the relevant files from the revision r194985 to r194984, no panic occurs. Of course it could very well be that r194985 itself is not the issue, but triggers a problem somewhere else in the kernel. Kind regards, Hans > I got a panic after AP CPU launched on boot.
