Subject: Re: 3.4-rc: NETDEV WATCHDOG: eth0 (r8169): transmit queue 0 timed out

Hi,

The problem still exists in 3.4.4. I'm currently using 3.2.21, which is fine.
Unfortunately it is service affecting, after some time the machine
just froze. I'm using headless setup, so I can not tell if this causes
the problem (logs are empty). But I had with 3.2.x more than 30+ days
uptime and no problems or warnings whatsoever (dmesg and logs are
clear). I do not believe that I'm the only one with this problem,
r8169 is quite popular.
Is there anything what can I provide or try? I do not want to be stuck
on 3.2.x kernel.
