I have no idea what has gone wrong with this chipset during the
3.3 to 3.4-rc5 move.

Can you apply the patch below on top of current ethtool
(git://git.kernel.org/pub/scm/network/ethtool/ethtool.git) and see
if it is enough to compare the register dumps (ethtool -d eth0).

Everything seems normal and we should be able to see both link up and down
messages.

Ok. This is a firmware free chipset anyway. Nothing strange in the interface
stats (ethtool -S eth0) ?

You may have to narrow things. Can you check if the r8169.c at
036dafa28da1e2565a8529de2ae663c37b7a0060 behaves the same ?

I will follow up on this eventually, but it may take quite some time due
to interfering work.

Thank you for looking into it and giving directions,

I haven't had time to look further into it yet.  Just two minor findings:

(a) After update from 3.4-rc5 to 3.4, the problem persisted.

(b) Later I noticed that silent file corruptions on FireWire disks happened
and happen under 3.4-rc5 and 3.4, so I reverted into 3.3.1 which fixed
that issue.  Furthermore, since 6 days uptime of 3.3.1, the eth0 (r8169)
transmit queue time-out did never occur.

I have no idea whether the FireWire and networking issues might be somehow
connected, and I still lack time to investigate these issues (using Linux
only at home, not at work), but I will eventually get back to it.

Hi,

I have the same problem on 3.4.1 and 3.4.2 (3.2.x is fine)
interestingly enough, the problem occurs only once, then it is running fine
(3.4.1 and six days uptime)

Please send a complete dmesg including the XID line emitted by the

If you need something else just tell me.

Thanks in advance

The XID line should look something like :

[    8.925786] r8169 0000:03:00.0: eth0: RTL8168evl/8111evl at 0xffffc900050ec000, 00:e0:4c:68:00:1f, XID 0c900800 IRQ 51

(whence the 'XID' thing)

Please send a _complete_ dmesg. I won't bet it will solve anything but
it can't be more useless than the generic watchdog message.

Thanks.
Tomas Papan - June 12, 2012, 5:12 a.m.

After a month uptime of 3.3.1 without any problems, I rebooted into 3.5
six days ago.  The frequent "r8169 0000:0b:00.0: eth0: link up" messages
which I got with 3.4-rc5 and 3.4 no longer happen.  Whatever was wrong
with my system, it no longer is.  Either 3.5 fixed it or it was an issue
external to the kernel or even external to the PC.
