Hello,
I have try the 8168DP and it wouldn't hang. I think I need more information. Could you give the information about the motherboard and the version of BIOS. Besides, please use the realtek driver, and dump the MAC information by using "ethtool -d eth0". These are helpful to find out what happens. Thanks.
Best Regards, Hayes

Hello,
I've just tried to boot a new computer featuring a Realtek r8168 onboard (lspci calls it Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller [10ec:8168] (rev 04), see [1]) network chip with kernel 2.6.38-rc5 and current git. Both hang on boot just after USB device initialization and just before the kernel usually does DHCP. The previous 2.6.37 didn't hang on boot, but showed strange behaviour (only 10MBit half duplex on autonegotiation, tons of errors on the switch interface[2]) which is why I tried the newer kernel in hopes that there would be fixes.
I bisected the hang-before-dhcp bug down to commit 'r8169: magic.' (b646d90053f887c1bc243191e693a9b02d09f2c2, also see [1]). Since the commit really does its description justice and looks like some weird hardware magic, I'd like to ask the wizards on how to proceed with fixing it.
Ciao,
Alexander Wuerstlein.
[1] Kernel .config, lspci, bisect log: http://wwwcip.cs.fau.de/~snalwuer/kernel-r8169/ [2] the Realtek-supplied r8168 doesn't show those problems [3] feel free to criticise my Cc:, I wasn't quite sure...
