Tested this: booted to Windows, then shutdown, then unplugged comp from power for 10-15 secs, then started OSX - and all the same as before, net is connected, but not usable. Required another shutdown and start into OSX to get it working.
I'm willing to try to to compare initalization with r8169 Linux driver (https://github.com/t...realtek/r8169.c). What should I start with or what to try to compare? Carefully go through all init process or go straight to this rtl8168_hw_phy_config()? r8169 identifies my card as RTL_GIGA_MAC_VER_33, uses rtl8168e_1_hw_phy_config() and uses FIRMWARE_8168E_2 (tl_nic/rtl8168e-2.fw, have it from Ubuntu). What is a chance to brick my controller by experimenting with this?
EDIT: Just an update: shutdown after Windows and unplugging the power and ethernet cable and waiting for 30 secs did the trick. Next boot to OSX resulted in working net.
you'll have a hard time trying to track down the error, in particular because Realtek's 8.035.00 driver doesn't separate the firmware from the code at all. Everything is packed into that giant function rtl8168_hw_phy_config. The chance of bricking the NIC can't be ruled out and we don't know what the firmware does.
But I have a better idea. You could get a copy of Realtek's current Linux driver (version 8.035.00) and test it under Linux. http://126.96.36.199...3&GetDown=false
If it shows the same issue with regard to Windows as under OS X then you could contact their technical support and hopefully they will fix it for us.
Can you provide me two debug logs. One when network is working fine, and one after you rebooted from Windows and the network is dead. In the last case please also open Network Utility and watch the number of packets transferred as they are updated by a hardware statistics dump of the NIC. This allows us to take a look at the NIC's internal state.
