[fedora-india] Realtek driver problems

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 rtl8139_get_stats is called rtl8139_get_stats is called rtl8139_get_stats is called rtl8139_get_stats is called rtl8139_get_stats is called pci 0000:04:03.0: PCI INT A disabled pci 0000:04:03.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 Device enabled ---------------------------------------------------------------- Base 0 Starting Address = 9c00 End Address = 9cff Length = 256 This Port is I/O mapped.
