I just bought a lenovo thinkpad edge 15. The eth controller is:

09:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI
Express Gigabit Ethernet controller (rev 03)
09:00.0 0200: 10ec:8168 (rev 03)

the driver in use is r8169

The problem is when i try to do a very huge data transfert over the gigabit
network: in the syslog i can see the river keeps spam things like:

and after some times (let's say 30 seconds but this vary also depending on the
speed transfert) the machine self reboot. The reboot is not clean of course.

I tested it with both an NFS and samba based trasfert, the same happens, but
with NFS the self reboot happens earlier i guess becouse the transfer speed is
higher. For the record the speed should be at least 40MBs/sec, at least this is
the speed i see when using windows (sorry, jut for test) and transferring from
the same samba server. In linux i can reach less then half the speed before the
machine self reboots.
