Ooops. Sorry. It's 2.6.12-rc1 but the same behaviour on 2.6.10 and 2.6.11.

You might be having interrupt routing problems, have you tried
pci=noapic as a boot parameter?
The data corruption is puzzling.
I didn't but I'll tomorrow.
eth3 is autonegotiated at 100 Mbps FDX.
Trying to forward packets through eth3 causes corruption of packets.
I've got 'Corrupted MAC on input' trying to download (or copy) something
using scp. Using ftp doesn't emit any error, but all files downloaded
are apparently corrupted.
After that I've tried to disable all off-loading. In this case no error
is visible but all download stalls forever.
How did you disable all offloading? With ethtool? Did you disable TSO
and TX/RX checksumming? You left scatter gather on, right?
Well. Actually I did this:
# ethtool -K eth3 rx off tx off sg off tso off
Is this problem related only to e1000 driver or any GigE cards? Is
there
any fix available?
Can you try the card in another (non opteron) machine? Does your
opteron machine pci bus support PCI-X/133?
I did testing on Wi****s 2K3 and it worked perfectly on the same machine.
If we can reproduce this we can likely get a fix, but without a
reproduction its unlikely because we haven't seen problems like this
around here.
