Hi,
I have an older AMD Phenom II motherboard with a new HD6450 to replace
an older card that failed. While video works fine with this new card,
it somehow causes the ethernet to fail. I've tried the card in the two
different x4 slots that are available, and it doesn't make a
difference.
This is an onboard ethernet controller that was otherwise working
fine. There's just no link light, and while I can configure it
manually with ifconfig, it never detects a link.
I can get it to work temporarily with another ethernet card, but this
was pulled from another machine.
Could this just be a general incompatibility? Or is there perhaps
something I can change? I tried investigating the computer's BIOS and
there really isn't much to change in terms of IRQ assignments or
otherwise.
Since the computer and Linux recognizes it, maybe there's something
more that can be done? Maybe loading a different rtl8169 driver would
work differently?
