I have this cheap "ENCORE 10/100Mbps Fast Ethernet PCI Adapter" which comes with its own driver that compiles to 'sundance.ko' and performs bad (30% packet loss) on a fully updated CentOS 4.4 box. This brand, model and driver have worked OK for me on some other CentOS installations, none of which are 4.4. Short of replacing the board, which you can bet I will do, can anybody provide me with some hint? Would CentOS Plus offer any different situation? 00:0a.0 Ethernet controller: Sundance Technology Inc / IC Plus Corp IC Plus IP100A Integrated 10/100 Ethernet MAC + PHY (rev 31) Subsystem: Sundance Technology Inc / IC Plus Corp: Unknown device 0201 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV+ VGASnoop- ParErr- Stepping- SERR+ FastB2B- Status: Cap+ 66Mhz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 32 (2500ns min, 2500ns max), Cache Line Size 08 Interrupt: pin A routed to IRQ 169 Region 0: I/O ports at bc00 [size=128] Region 1: Memory at febff400 (32-bit, non-prefetchable) [size=512] Expansion ROM at ffff0000 [disabled] [size=64K] Capabilities: [50] Power Management version 2 Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=0mA PME(D0-,D1+,D2+,D3hot+,D3cold+) Status: D0 PME-Enable+ DSel=0 DScale=2 PME- TIA -- Eduardo Grosclaude Universidad Nacional del Comahue Neuquen, Argentina -------------- next part -------------- An HTML attachment was scrubbed...
