Hi, my new board (GA-8ST, P4, single-CPU, SiS Chipset) has a RealTek 8139 on board which isn't working with Linux 2.4.xx (tried 2.4.18, 2.4.19, 2.4.20rc1 and 2.4.20rc2). I've attached lspci, dmesg and config from my 2.4.20rc2 and from a 2.2.20, where the NIC is working like a charm.... 2.2.20: eth0: RealTek RTL8139 Fast Ethernet at 0xe000, IRQ 11, 00:20:ed:3a:f5:ee. 2.4.20-rc2: 8139too Fast Ethernet driver 0.9.26 eth0: RealTek RTL8139 Fast Ethernet at 0xd082f000, 00:20:ed:3a:f5:ee, IRQ 19 eth0: Identified 8139 chip type 'RTL-8139C' eth0: Setting 100mbps full-duplex based on auto-negotiated partner ability 45e1. NETDEV WATCHDOG: eth0: transmit timed out eth0: Tx queue start entry 4 dirty entry 0. eth0: Tx descriptor 0 is 00002000. (queue head) eth0: Tx descriptor 1 is 00002000. eth0: Tx descriptor 2 is 00002000. eth0: Tx descriptor 3 is 00002000. I've also tried 8139cp, but the driver says that my nic isn't a 8139C+ and I should try 8139too instead - with no success as you can see.... If I can help any further, let me know (please with an additional personal addressed E-Mail). Bye Michael
