Latest working kernel version: Earliest failing kernel version: Distribution: Gentoo Hardware Environment: x86, x86_64 Software Environment: Problem Description: there is no 'device' link created for the sc92031 nic in sysfs under its respective directory '/sys/class/net/eth?' thus making it impossible to search up the device tree using udev. In my special case, persistent udev net rules cannot be generated by the respective gentoo udev script due to its dependency upon the udev 'DEVICES' key which cannot be determined because of the impossibility to search up the tree. Steps to reproduce: 1) install silan sc92031 (or realtek 8139D) nic in your pc 2) recompile and install kernel 2.6.24 (sysfs enabled) with sc92031 driver either in-kernel or as a module 3) reboot or load sc92031 module 4) make sure sysfs is mounted on /sys 5) look into the respective '/sys/class/net/eth?' directory
