You're not running netatalk on this box, are you?  If I run netatalk on my
x86 with 2.0.35, eepro100, it will start doing this.  It will work at
first, but generate huge amounts of TX timeouts and 'Trying to restart the
transmitter'.  Then, it seems the driver gives up and suspends the TX
unit.  You can reset it by:

1.  take down eth0
2.  modprobe -r eepro100
3.  modprobe eepro100
4.  restart eth0
