I'm seeing the same when removing/inserting network drivers frequently, ixgbe does
the same thing: (git://davem/net-2.6.24)
ixgbe 0000:01:00.0: (PCI Express:2.5Gb/s:Width x8) 00:1a:64:3b:81:c3
ixgbe 0000:01:00.0: MAC: 0, PHY: 0, PBA No: d95854-003
ixgbe 0000:01:00.0: Intel(R) 10 Gigabit Network Connection
net eth2: device_rename: sysfs_create_symlink failed (-17)
but I can't make it throw a stack trace.
perhaps one of the sysfs knowledgeable people can take a look at this. We might be
doing something wrong in e1000e / ixgbe at setup time, but I have no idea what.

I think the report belongs to udev.
It tries to rename network devices even if they already
have the name it desires.

To reach this path you need to run the equivalent of:
ip link set eth0 name eth1
I have seen this a bit and my memory is that the error is generally
harmless. It is trying to create a symlink with the same name as the
directory or something like that. Which makes with one setting of
CONFIG_SYSFS_DEPRECATED but not the other.
So I don't believe this is a driver bug, and I suspect the renames
come from using something like /etc/mactab which forces ethernet
devices with specific mac addresses to specific ethernet device
names.
With whatever is sitting in my development tree I'm pretty certain
this error isn't present. I don't recall if I did anything specific
to fix this though. In particular I don't recall if this still
happens with gregkh's queued sysfs patches applied.
