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.
