During system startup, there are problems with the hardware detection which need to be analysed.


The value for the udev log level can be set in the udev configuration file /etc/udev/udev.conf. The default setting is:


Change the value from "err" to "debug" and reboot. After the boot has finished, the verbose messages from udevd can be found in /var/log/messages. If needed, the log level can be set back to the default for the running session through

udevcontrol log_priority=err

To permanently set it back to the default, edit /etc/udev/udev.conf again.
