I've got it working with 10Mbps full-duplex now. Here are the lines from modprobe.conf:

 alias eth0 r8169
 options eth0 use_dac=0 media=0x2


It makes sense. use_dac=1 is reported to badly fail on amd64 most of
time.

I didn't see any crashes or hangs with use_dac enabled (or rather, not disabled).

I haven't tried use_dac=1 with media=0x2, though. Maybe that would give enough traffic to crash or hang my box.

Can you try 2.6.10-rc2 +
http://www.kernel.org/pub/linux/kernel/people/jgarzik/patchkits/2.6/2.6.10-rc2-netdev1.patch.bz2
 +
http://www.fr.zoreil.com/linux/kernel/2.6.x/2.6.10-rc2-mm1/r8169-250.patch +
http://www.fr.zoreil.com/linux/kernel/2.6.x/2.6.10-rc2-mm1/r8169-255.patch

No, that suffers from the same problems.

How do these patches differ from those in 2.6.10-rc2-mm2?

Let me know if there are any other patches you want me to try.

Is it an option for you to disable ACPI, remove the media specification
and simply issue an 'ethtool eth0' a few tens of seconds after insertion
of the module ?

Sadly my box won't boot, if I disable ACPI.

It takes ages to negotiate here (Netgear switch + 8169 PCI adapter).

It seems to negotiate pretty quickly with my DSL router. Less than a second, I'd say. I can time it a bit more exactly, if it would help.

From your ethtool patch, it looks like I have a 8110. I did search their specs for version registers, etc., but I could not see them. Where did you get your datasheet from for the 8110?

Thanks, bye, Rich =]
