@Dave: I notice that in your RfKill.txt attachment the wirelss lan device is soft blocked. I also note that the following patch went into the kernel between your working and non-working versions:
commit 466449cfe797b8a5d82d25d0e0e08426d8dfba19 Author: Lee, Chun-Yi <joeyli.ker...@gmail.com> Date: Mon Dec 13 10:02:41 2010 +0800 acer-wmi: Initialize wlan/bluetooth/wwan rfkill software block state So perhaps what's happened is that your firmware state indicates that wifi should be disabled, but prior to that patch the kernel wasn't checking the bios to get that state. Do you have a wifi hotkey on your machine? What happens if you press it? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/710738 Title: Regression latest kernel breaks my Atheros AR5001 wifi -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
