Steffen, I am getting mostly transmit errors on a 3c597 Fast Ethernet card. It is EISA, not PCI. Here is some of the logs with verbosity turned up a bit:
eth3: using default media 100baseTX [372] eth3: Initial media type 100baseTX. eth3: setting half-duplex. [372] eth3: vortex_up() irq 9 media status 8882. <intr> eth3: Media 100baseTX has link beat, 8882. eth3: transmit timed out, tx_status 00 status 8000. diagnostics: net 0c80 media 8882 dma ffffffff fifo 0000 eth3: transmit timed out, tx_status 00 status 8000. diagnostics: net 0c80 media 8882 dma ffffffff fifo 0000 eth3: transmit timed out, tx_status 00 status 8000. diagnostics: net 0c80 media 8882 dma ffffffff fifo 0000 eth3: transmit timed out, tx_status 00 status 8000. diagnostics: net 0c80 media 8882 dma ffffffff fifo 0000 [378] eth3: vortex_close() status 8000, Tx status 00. [378] eth3: vortex close stats: rx_nocopy 0 rx_copy 0 tx_queued 0 Rx pre-checksummed 0. Here is what I got from the registers: NetworkDiagnostic (net): txEnabled, rxEnabled, statisticsEnabled MediaStatus (media): auiDisable, linkBeatDetect, linkBeatEnable, crcStripDisable IntStatus (status): register window 4 selected I am seeing /proc/interrupts incrementing, so at least some interrupts are getting to the card. 'tc -s qdisc' reports 4 requeues on 13 packets sent. 'ifconfig' reports 13 tx packets, 11 tx errors, 11 tx dropped (no overrun, carrier, or collision errors). I can do the legwork on debugging this. What should I investigate next? - Matthew
