Acer Aspire as 1410 ethernet lan problems

Hi,

I recently bought an Acer Aspire as 1410.

Its onboard ethernet card is Atheros AR8131 PCI-E Gigabit.

The first distros I tried were:
Moblin - which had no problem and worked like a charm.
And Ubuntu which installed drivers for neither my ethernet card nor my wireless one, however I could see both of them on "lspci" output.

I went for Arch and everything looked ok the card showed on lspci and ifconfig looked normal.
After plugging my lan cable however everything went crazy ...
ifconfig output for eth0 was something like:

RX packets: 484222754
Erroneous packets: 667653421

and this doubled every second ...

My first thought was there is something wrong with the driver so I downed eth0 and got this:
Disabling IRQ #16

After which the card no longer showed on my lspci output ...
Reboot did not fix the problem so I went back to Moblin which to my amazement did not find the card anymore ...

I tried windows which also found nothing.

So I went back to my reseller and swaped my netbook for a new one because I thought it was defective.

However the same thing happens on the new one ...
On Arch after downing the interface for the first time it disables IRQ 16 and I can't see the card any longer ...

I tried booting with the "irqpoll" kernel option which made the card show up on lspci output, but after a "/etc/rc.d/network restart" I got: Disabling IRQ #16 - again and now even "irqpoll" can't make it 'come back' ...

I am totally confused now to the point that I'm afraid to uninstall Arch and see if something else finds the card sad

Any help/ideas/advice will be greatly appreciated.

Thanks in advance

Re: Acer Aspire as 1410 ethernet lan problems

Progress !

I reverted to the default bios settings and lspci shows the card again.

I don't know what the kernel does when I try to down eth0 but it sure seems broken to me, so if anyone has a similar problem with 2.6.30 kernel try reverting to your bios default settings.

Still if anyone has any suggestions they would be greatly appreciated smile

Under 2.6.20.31, it should work fine with atl1c. To make it work with .30, you have to compile the module atl1e - here is a HowTo (scroll down a bit).
