Hmm, there was similiar report but I couldn't reproduce this on
my box. In fact I'm out of idea why it happens. Since I have no
access to datasheet I'm not sure what can be done at the moment.
Even a developer in Atheros answered that changing mainboard would
be the first step to diagnose the issue. :-(

There are a couple of magic values related with PHY in Linux driver
which I didn't want to include as I don't understand what it does.
Do you use 10baseT media? Would you show me the output of
"ifconfig ale0"?
