I was able to install 12.04 ok on my Acer eMachines, but whenever it is unplugged from the LAN connection, the whole system freezes. I've installed the latest updates and it's still behaving the same.

I am not sure where to start to troubleshoot the issue, anyone here has any idea?

Info about my network cards:

06:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)
07:00.0 Ethernet controller: Atheros Communications Inc. AR8152 v2.0 Fast Ethernet (rev c1)

The driver could be doing something wrong and holding spinlock.

Do you see atl1c listed when you run lsmod? If so, try this before unplugging:

    # rmmod atl1c

Does it still hang?

Yay, thanks Bracken!! Googling about the atl1c, I saw that my issue had actually been answered in the past,… Do you think I should install alx module now? –  user67011 Jun 6 '12 at 22:08
It's certainly worth a try. –  Bracken Jun 9 '12 at 19:50
