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?
