Monkey boy needs help! Transmit timed out:...

[Gisli Ottarsson]

Please help me solve my eepro100 problem which I outline below.

Hardware:

 Doorstop 486 PCI, Intel Saturn motherboard, 16Mb RAM :-(
 Intel 82557 EtherExpressPro100B 

Kernel:

 Linux 2.2.13 stripped to the bare essentials.  No module support.
 Compiled with gcc version 2.95.1

Driver versions tested:  

  eepro100.c:v1.09l 8/7/99  (latest?)
  eepro100.c:v1.06 10/16/98 (standard with 2.2.13)
  eepro100.c:v1.05 10/16/98 (used below)

  The frequently repeated suggestion to set the value of
  multicast_filter_limit to 0 or 3 was tried (by editing eepro100.c)
  but this did not affect my problem.

Boot info:

eth0: Intel EtherExpress Pro 10/100 at 0xd00, 00:90:27:06:1E:C3, IRQ 11.
  Board assembly 701738-003, Physical connectors present: RJ45
  Primary interface chip i82555 PHY #1.
  General self-test: passed
  Serial sub-system self-test: passed
  Internal registers self-test: passed
  ROM checksum self-test: passed (0x24c9f043).
  Receiver lock-up workaround activated.
  .
  .
  Bringing up interface eth0 succeeded

Problem:

My furst action upon login is to ping a network peer.  I get:

  # ping 10.0.0.1
  PING 10.0.0.1 (10.0.0.1): 56 data bytes
  eth0: Transmit timed out: status 7050  0000 at 0/15 command 0001a000.
  eth0: Trying to restart the transmitter...
  <repeated ad infinitum, until I 'ifdown eth0'>

Diagnosis:

I have downloaded the eepro100-diag and mii-diag software.  At the
risk of giving the false impression that I have a clue, here is some
of the output I have generated.  Additional diagnosics available upon
request.


# ifup eth0

# ./mii-diag
Using the default interface 'eth0'
Basic registers of MII PHY #1: 3100 7829 02a8 0150 05e1 0081 0000 ffff.
 Basic mode control registers 0x3100: Auto-negotiation enabled.
 Basic mode status registers 0x7829 ... 782d.
   Link status: previously broken, but now reestablished.

# ./mii-diag
Using the default interface 'eth0'
Basic registers of MII PHY #1: 3100 782d 02a8 0150 05e1 0081 0000 ffff.

 You have a link beat, and everything is working OK.

IMPORTANT NOTE: This information has primarily been hand typed from
the screen of the ailing machine and although I have exercised great
care, some errors may have crept in.


Many thanks for your attention.
