While booting a nforce (first generation) based computer with udev module
loading disabled and loading nvidiafb.ko later on from console (modprobe
nvidiafb) I experience the following trace.
This does not happen every time nor does it happen when nvidiafb gets
loaded by udev.
Kernel is 2.6.24 from kernel.org with a few patches:
- squashfs3.3
- patches referred to by Raphael in http://lkml.org/lkml/2008/1/27/292
Below, trace, lspci and parts of my config.
Regards,
Bruno
