Dual via-rhine on EPIA PD6000E

Dual via-rhine on EPIA PD6000E

[Wojciech Kromer]

Hi. I have two differnent via-rhine on EPIA board. Second one is now 
working on my 2.6.15 kernel.

Why there are different io adresses in lspci dmesg and ifconfig?
Any idea why it's not working???


Here are some additional info:

PS  now second cable is disconnected, but there was a link on eth1 too

There is a difference between ioports and iomem.

/proc/iomem:
cfffc000-cfffcfff : 0000:00:04.0
  cfffc000-cfffcfff : sis900
/proc/ioports:
d400-d4ff : 0000:00:04.0
  d400-d4ff : sis900
ifconfig:
eth1      Link encap:Ethernet  HWaddr 00:0A:E6:98:ED:D7  
          Interrupt:201 Base address:0xd400

"Not working" is vague. No packet transmission even though the link is 
active?

^^ ioports vs iomem!

Of course I know, but look at this:

# cat /proc/ioports
d000-d0ff : 0000:00:0f.0
  d000-d0ff : via-rhine
e400-e4ff : 0000:00:12.0
  e400-e4ff : via-rhine

# cat /proc/iomem  
de000000-de0000ff : 0000:00:0f.0
  de000000-de0000ff : via-rhine
de002000-de0020ff : 0000:00:12.0
  de002000-de0020ff : via-rhine

from ifoconfig:
eth0: Interrupt:10 Base address: *0xe000*
eth1: Interrupt:11 Base address: *0x4000* <<is it I/O or mem ???

Huh! Now it started. But it's first time from four days. Before it i had 
no frames received.

ioport.
ioports only go up to 0xffff, and iomem does not normally start below 
0xffff.

0x4000 and 0xe000 look strange though (they don't match /proc/ioports).
