Public bug reported:
Binary package hint: linux-source-2.6.20
You need system with r8169 card (Realtek Gigabit card)
1. start system with ethernet cable _disconnected_
2. connect ethernet cable
- system says no link detected - not true
To overcome this you have to
1) unload driver - rmmod r8169
2) load the driver again - modprobe r8169
after that opreations driver sees link
important pieces from dmesg:
loading driver
[ 4.184000] r8169 Gigabit Ethernet driver 2.2LK loaded
[ 4.184000] ACPI: PCI Interrupt 0000:03:00.0[A] -> GSI 18 (level, low) ->
IRQ 17
[ 4.184000] PCI: Setting latency timer of device 0000:03:00.0 to 64
[ 4.184000] eth0: RTL8168b/8111b at 0xf88b8000, 00:18:f3:ee:2f:2a, IRQ 17
init driver (ethernet disconnected)
[ 16.372000] r8169: eth0: link down
[ 17.252000] NET: Registered protocol family 10
[ 17.252000] lo: Disabled Privacy Extensions
[ 17.252000] ADDRCONF(NETDEV_UP): eth0: link is not ready
at this point ethtool says that there is no link detected (machine at the other
side of the cable says otherwise)
unloading driver:
[ 5641.472000] ACPI: PCI interrupt for device 0000:03:00.0 disabled
and loading it again:
5644.756000] r8169 Gigabit Ethernet driver 2.2LK loaded
[ 5644.756000] ACPI: PCI Interrupt 0000:03:00.0[A] -> GSI 18 (level, low) ->
IRQ 17
[ 5644.756000] PCI: Setting latency timer of device 0000:03:00.0 to 64
[ 5644.756000] eth0: RTL8168b/8111b at 0xf8d42000, 00:18:f3:ee:2f:2a, IRQ 17
[ 5644.804000] r8169: eth0: link down
[ 5644.804000] ADDRCONF(NETDEV_UP): eth0: link is not ready
[ 5646.380000] r8169: eth0: link up
[ 5646.380000] ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
[ 5656.756000] eth0: no IPv6 routers present
and now link is properly detected
