Driver development for the Realtek RTL8129/8139

Problem: network unreachable

Hi,

I have a laptop with the RTL8139 and a kernel 2.4.19 (SuSE 8.1).
I tried the versions 1.20 and 1.22 of rtl8139.o, but didn't manage to
connect to the network.

It didn't work either with the 8139too.o driver from SuSE or Mandrake.

I found a similar problem in the list archive from September, but no
solution.

With the v1.22, the messages in /var/log/messages are:

---
dhcpd[2054]: terminating on signal 15
kernel: eth0: no IPv6 routers present
kernel: eth0: Transmit timeout, status 0c 0005 media 10.
kernel: eth0: RTL8139 Interrupt line blocked, status 5.
kernel: eth0: Tx queue start entry 4  dirty entry 0, full.
kernel: eth0:  Tx descriptor 0 is 0008a24e. (queue head)
kernel: eth0:  Tx descriptor 1 is 0008a04e.
kernel: eth0:  Tx descriptor 2 is 0008a046.
kernel: eth0:  Tx descriptor 3 is 0008a24e.
kernel: eth0: MII #32 registers are: 1100 782d 0000 0000 01e1 41e1 0001
0000.

Can anybody help?

Thanks,

You have a problem with the CardBus IRQ code.
This problem isn't related to the realtek driver version -- the NIC driver
doesn't set up the IRQ mapping.

The solution is to fix the CardBus bus bridge configuration.  It
usually isn't necessary to configure this by hand, but may be on a few
specific laptop models.

Yup, guess why I had to add messages like this to the drivers.
