[tulip] Interrupt problem (?) with OvisLink Fast Ethernet PCMCIA

[Guido Bartsch]

Hello,

we have difficulties getting this CardBus card to work with the
2.4.0test5-pre3 driver "Linux Tulip driver version 0.9.8 
(July 13, 2000)" (from tulip_core.c)

According to /proc/pci, it has a DECchip 21142/43 (rev. 41) on board,
and a "Abcom Systems Inc: Unknown device ab01" as a subsystem.

The tulip driver successfully recognizes the card when inserted. 

The output from dmesg shows:

cs: cb_alloc(bus 2): vendor 0x1011, device 0x0019
PCI: Enabling device 02:00.0 (0000 -> 0003)
Linux Tulip driver version 0.9.8 (July 13, 2000)
PCI: Setting latency timer of device 02:00.0 to 64
eth0: Digital DS21143 Tulip rev 65 at 0x1000, 00:E0:98:23:00:5C, IRQ 13.
eth0:  EEPROM default media type Autosense.
eth0:  Index #0 - Media MII (#11) described by a 21142 MII PHY (3)
block.
eth0:  MII transceiver #0 config 3000 status 7809 advertising 01e1.
eth0: Setting full-duplex based on MII#0 link partner capability of
41e1.

mii-diag shows:

Using the default interface 'eth0'.
Basic registers of MII PHY #0:  3000 782d 0040 6212 01e1 41e1 0003 0000.

 You have link beat, and everything is working OK.

tulip-diag shows:

Index #1: Found a Digital DS21143 Tulip adapter at 0x1000.
 Port selection is MII, full-duplex.

  The Rx process state is 'Waiting for packets'.
  The Tx process state is 'Idle'.
  The transmit threshold is 128.

   Tx complete indication.
   Tx out of buffers indication.
   Rx Done indication.

After trying a ping (which doesn't work - no response, and ethereal on
the destination host doesnt show any decodable packets) tulip-diag
shows:

The card doesn't seem to generate any interrupts: /proc/interrupts
shows:

Perhaps interrupt sharing doesn't work? 

I would appreciate any suggestions.

Thanks,
