RTL8139 driver hangs up

Mon Mar 6 09:05:08 2000

Hi!
	I have been using the rtl 8139 driver v 1.07 with a 2.2.13
kernel (this is the default that comes with GNU/Debian 2.2 frozen). I
have experienced some trouble with the driver. Namely, the 
card stops existing as far as the real world is concerned: it becomes
invisible to the local network (I cannot ping it from other hosts in the
same net, and I cannot ping those hosts from it,even though the LED at
the hub flashes with the ping requests). The way to solve this up to now
has been to issue an ifconfig eth0 down;rmmod rtl8139;insmod
rtl8139;ifconfig eth0... up

	The output from the provided diagnostic program is:
# ./rtl8139-diag -a

Index #1: Found a RealTek RTL8139 adapter at 0xe800.
The RealTek chip appears to be active, so some registers will not be
read.
To see all register values use the '-f' flag.

Parsing the EEPROM of a RealTek chip:
PCI IDs -- Vendor 0x10ec, Device 0x8139, Subsystem 0x149c.

The RTL8139 does not use a MII transceiver.
It does have internal MII-compatible registers:
Basic mode control register   0x780d.
Basic mode status register    0x0000.
Autonegotiation Advertisement 0x05e1.
Link Partner Ability register 0x0000.
Autonegotiation expansion     0x0000.
Disconnects                   0x0000.
False carrier sense counter   0x0000.
NWay test register            0x0000.
Receive frame error count     0x0000.

	Sorry for the long outputs, but I don't know what parts might be
relevant.

	Thank you for your time,
	José
