Hello, I'm trying to use Fedore Core 1 and I can't setup correctly my NIC. It's a simple CardBus PCMCIA card, Realtek 8139C in IBM Thinkpad 600. pcmcia-cs's doing a good job and I hope my card is recognized correctly: eth0: RealTek RTL8139 Fast Ethernet at 0xc6906000, 00:02:44:4c:ed:05, IRQ 11 eth0: Identified 8139 chip type 'RTL-8139C' divert: freeing divert_blk for eth0 8139too Fast Ethernet driver 0.9.26 I can set IP, netmask, route and I can use dhcp when I'm trying dhcp server on my gw and interface getting number correctly from server, but that's all. I haven't any connection with any host, all packets are lost. Kernel's giving me something like that: //Hub 100Mbps 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. eth0: link up, 100Mbps, full-duplex, lpa 0x45E1 All cables and devices are OK, because I'm sending this now via this network and devices but I'm using Foo-LiveCD distribution, not Fedora Core 1. I tried another hub/switch and situation is exactly same like last time: //Switch 100Mbps NETDEV WATCHDOG: eth0: transmit timed out eth0: Tx queue start entry 20 dirty entry 16. 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. eth0: link up, 10Mbps, half-duplex, lpa 0x0000 Little more information about this hardware: Bus 4, device 0, function 0: Ethernet controller: PCI device 10ec:8139 (rev 16). IRQ 11. Master Capable. Latency=64. Min Gnt=32.Max Lat=64. I/O at 0x4800 [0x48ff]. Non-prefetchable 32 bit memory at 0x10c00000 [0x10c001ff]. I'm trying on default kernel from FC1 and I tested lastest 2.6.x kernel from FC2 development tree, I also update pcmcia-cs to lastest version and still without network. Cheers, Pawel
