[LUG] Realtek driver problem

 
Hi All,

 I am currently working on the realtek driver available in 
http://linuxgazette.net/156/jangir.html.

 When I run the driver, pci_request_regions is erring out as :
ifconfig rtl8139 up
SIOCSIFFLAGS: Device or resource busy
[root@asdlab realtek]# dmesg | tail -50
rtl8139_get_stats is called
