[Bug 76489] Re: network device, module r8169, fails with NETDEV WATCHDOG: eth0: transmit timed out

[Lasse]

Report.sh does not work for me either:

lasse at backend:~$ sudo ./report.sh good
Failed to find any device with vendor ID 10ec
lasse at backend:~$

yet:
lasse at backend:~$ lspci -nn|grep 10ec
02:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller [10ec:8168] (rev 02)
lasse at backend:~$

I get this error several times a day, since I'm running a mythtv backend
with heavy traffic:
