[hardy] kernel 2.6.24-12 breaks wireless (Atheros AR242x)

[TDB]

Recent update to kernel 2.6.24-12-generic from 2.6.24-11-generic breaks wireless (atheros chipset). No ath0 interface. Works flawlessly with 2.6.24-11. there seems to be related dmesg output:

confirmed here on acer 5520 running this atheros. I have tried also the source madwifi driver and it doesn't work. Is this related related to the addition of acer_acpi in the latest kernel? at least earlier I could manually install, but no longer

[TDB (michael-baranov)]

@thompa: can you please grep your dmesg for the same error messages as I
posted earlier? Thanks.

above my full output.
I noticed though this:

The ath-pci seems to be the one I compiled if i am not mistaken. i had to do this when I was in 2.6.24-11 to get it working. I'm wondering since the kernel change if I need to start from scratch. I may try a new build since the acpi change if any....

[thompa (thom-tendata)]

attached is my dmesg from 2.6.12-11 which works.
relevant is maybe:

This fix the issue an make load the module
/sbin/rmmod ath_pci ath_rate_sample ath_hal wlan_scan_sta wlan_scan_ap wlan 2>/dev/null
/sbin/insmod /lib/modules/2.6.24-12-generic/madwifi/wlan.ko
/sbin/insmod /lib/modules/2.6.24-12-generic/volatile/ath_hal.ko
/sbin/insmod /lib/modules/2.6.24-12-generic/madwifi/ath_pci.ko autocreate=ap

this a work to modprobe blacklist?

[Lionel Dricot (ploum-deactivatedaccount)]

Is this bug still valid in Hardy with 2.6.24-17 ?

[Fabián Rodríguez (magicfab)]

I can confirm this still happens in 2.6.24-17. I am marking other duplicate bugs, editing descriptions to match and cleaning up.

[Fabián Rodríguez (magicfab)]

Sorry, I mean -18.

[Fabián Rodríguez (magicfab)]

Please disregard my last 2 comments. I had this issue confused with another similar one.

I am now going through all bugs I marked as duplicates and unmarking/keeping marked as appropriate.

I was a bit fast with my gun on this one, apologies to all involved.

[Simon Jagoe (azriphale)]

I am experiencing this problem with the 2.6.24-19 kernel and restricted modules. I have found that post-install, running depmed fixes the issue, but I was wondering if there is a way to get around the problem during install. I am performing an unattended installation (using debconf preseed), and need to have a working system without any manual intervention (as I need to deploy multiple systems in this way).

dmesg output is below (but not very exciting -- it is the same as has been posted above before)

$ dmesg | grep ath_pci
[ 30.085096] ath_pci: Unknown symbol _ath_hal_attach
[ 30.085316] ath_pci: Unknown symbol ath_hal_process_noisefloor

$ lspci | grep Wireless
03:00.0 Ethernet controller: Atheros Communications Inc. AR5212 802.11abg NIC (rev 01)

Does anybody know if this works with the 2.6.24-18 kernel and restricted modules?

[Simon Jagoe (azriphale)]

I think I can now confirm that -18 does not have this problem.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

[Launchpad Janitor (janitor)]

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.

[Brad Figg (brad-figg)]

This bug was reported a while ago but there hasn't been any recent comments or updates. Is this still an issue with the latest pre-release of Jaunty 9.04? Refer to http://www.ubuntu.com/testing/jaunty/beta . Please let us know.
