Subject: 3.14.1 network issue with rtl81xx chip

Hello,

On two boxes with rtl network chip I see connections going down.
An ifdown eth0;ifup eth0 fixes this.

3.14.1 has the issue.
How can I fix this more elegantly?

Below is info from both boxes from lspci and dmesg:

02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 03)

01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06


eth0: RTL8168d/8111d at 0xffffc9000060c000, x, XID 081000c0 IRQ 41

eth0: RTL8168evl/8111evl at 0xffffc9000001c000, x, XID 0c900800 IRQ 51

Do you notice netdev watchdog messages in the kernel log ?

Does it qualify as a (recent ?) regression or is it a fresh new setup ?

No suggestion yet.

I do not see messages that look like that.

This machine has been running for over a year and some time ago the
problem occurred.
Same for the other problem machine which is even older.
