Hello Maillist,

Im using FreeBSD-CURRENT (from 01122008 snap from cvs) and got looped notice
in dmesg buffer when LAN Ethernet generate some traffic:
..
ale0: could not disable Tx/Rx MAC(0x00000008)!
ale0: DMA read error! -- resetting
..
ale0: could not disable Tx/Rx MAC(0x00000008)!
..
with flapping interface (link going to down and back up).


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. :-(

ifconfig ale0 -txcsum -rxcsum -tso and forcing link for media 10BaseT/UTP is
in vain.


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"?

Under small traffic flow ale0 work is fine without errors. Somebody meet with
like similar prombel on Asus eee pc 901 ? Thanks


Anyway, I'll let you know if I mange to find a clue to the issue.
