The Linux kernel is trying to load the module for the device 'net-pf-10' and it is failing. Please read 'devices.txt' in /usr/src/linux/Documentation/ and find out for what that is required for. You can switch off this probe by adding this line in your /etc/modutils/alias, `alias net-pf-10 off' and then doing a 'update-modules'.

net-pf-10 is required for IPv6, anyway ...
