[SOLVED] LAN (atl1c) not working with 2.6.32.x kernel

Nicky726 · 2010-01-10 16:15:34

Hello,
on my EEE PC, after upgrade to 2.6.32 kernel (.2 or .3) ARCH stock, my LAN is not working. It is not shown in lspci, nor there is eth0 in ifconfig -a.

This is of cat /var/log/kernel.log | grep -i atl. 16.47 is with .32, 16.59 is with .31 kernel:

Jan 10 16:47:28 kawagiri kernel: atl1c 0000:01:00.0: PCI INT A -> GSI 19 (level, low) -> IRQ 19

with .31 kernel:

lspci | grep -i net
01:00.0 Ethernet controller: Attansic Technology Corp. Atheros AR8132 / L1c Gigabit Ethernet Adapter (rev c0)
02:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)

I dit a bit of googling but didn't come to anything useful.

Any ideas?

Yes, it is simply broken. I have reinstalled 2.6.31 on my netbook. It's annoying, but the older kernel works fine. Let's hope 2.6.33 is better.

:-( any workaround? is the bug reported upstream?

icebadger · 2010-02-09 03:56:22

I am having the same trouble. I have a new install and went from version .30 to .32

How do I get the .31 kernel installed?

Hiya, I was having the identical problem with an Acer AspireOne D250 netbook using the atl1c kernel mod. The Arch Wiki entry for my netbook specifically has a workaround posted, though I believe it's applicable here:

http://wiki.archlinux.org/index.php/Ace … e_D250_LAN

With Archlinux 2009.08 the installation did not work from the beginning on an Aspire One D250. The LAN was not working properly. This could be traced down to the Kernel 2.6.30 which had broken network drivers. To get the LAN working, use the Archlinux core install. After installing Archlinux, get the Kernel 2.6.31 and the Kernel Headers on a USB stick and install it via "pacman -U". After rebooting, the LAN should work properly.

Hope this helps!

So it was broken in 2.6.30, they fixed it in 2.6.31 and then broke it again in 2.6.32?

Did you try toggling the wifi? With 2.6.32 the wifi toggle on my eeepc toggles the lan instead of the wifi. Once the lan adapter is showing in lspci it works as normal.

tvale · 2010-02-09 13:33:23

I've got that same hardware and everything works flawlessly. Perhaps what Wittfella said?

icebadger · 2010-02-10 22:42:51

I was able to get eth0 to show up, and get my wired connection working. I think the problem was, in the BIOS, I had bluetooth disabled. Even though my ethernet was enabled, that small bluetooth change did the trick.

I was able to use the wireless to do a Net install from the USB image, and update the kernel to .32

I have not tried disabling the bluetooth from BIOS yet to see if I loose eth0 again.

Hey, it seems to work! Saddly when wi-fi is disabled again, LAN disappears after reboot, but stays until rebooted. Guess it won't matter, as when on battery I usually use wifi too, and when using LAN, I usually am on AC. Thanks guys, seems its work-arounded till .33 (hope, it'll be fixed there once and for all).
