Thanks.

There seems to be a more recent bios for this motherboard. Is the second
8168b an add-on or is it a dual-port DH61HO ?

You are using x86 32 with PAE and slub where I use x86 64 with slab.
I am building a x86 32 bits test configuration for a 8168b right now.

Let's see what happened during the 3.4 .. 3.5 cycle in the r8169 driver:

- You may revert 7dbb491878a2c51d372a8890fa45a8ff80358af1 ("r8169: avoid NAPI
  scheduling delay.")

  I can see a napi rtl8169_poll failing to schedule rtl_slow_event_work
  when it is already scheduled on a different cpu, said rtl_slow_event_work
  running while rtl8169_poll is delayed and rtl8169_poll stomping on the
  IntrMask after rtl_slow_event_work did.

  It does not tell why the device does not recover after the netdev watchdog
  but it could be worth trying.

- You may revert 851e60221926a53344b4227879858bef841b0477 ("r8169: Config1 is
  read-only on 8168c and later.") as well.

  It changes the PMEEnable write ordering for the 8168b (RTL_GIGA_MAC_VER_17)
  and a few others chipset.
