dmesg output from kernel-2.6.29.6-217.2.16.fc11.i586 (with working wireless)
This problem is still present in the just-released kernel-2.6.30.8-64.fc11. This problem is still present in kernel-2.6.30.9-90.fc11. This problem is still present in kernel-2.6.30.9-96.fc11. I did some work with 'git bisect' on the mainline kernel, and according to this the first bad commit is c0380693520b1a1e4f756799a0edc379378b462a, 'airo: clean up WEP key operations'. Hi. Is bug fixed in new kernels? This bug is still present in kernel-2.6.30.10-105.2.4.fc11.i586 (and previous kernels between that and the last one I reported). Thank you for fast answer. Hmm, I forgot F11 still using 2.6.30 based kernel. Could you please check some newer releases from git tree or vanilla tarballs 2.6.31, 2.6.32 and if it not fixed 2.6.33-rcX. Neither 2.6.32 (compiled from git) nor 2.6.33-rc6 (nominal, compiled from git tip as pulled an hour or so ago) see the wireless properly. Created attachment 388068 [details]

Could you please test this patch? It's for 2.6.32. If may help, but if not it will provide verbose messages to allow diagnose problem more precisely.
The patch appears to fix the problem. With the patch applied, 2.6.32 sees our local wireless networks and connectivity appears to work fine. Chris, I send a slightly different (removed extra debug stuff) patch upstream, CCing you. Please reply with Tested-by mark to the email or speak loudly if patch not work. Through kernel stable tree patch will get to fedora. Thanks. I've just sent in a Tested-by: email message (hopefully in the right format). Let me know if more is needed, and thank you for running this down. Fedora 12 will update to 2.6.32.10 kernel, which include fix for that bug. To update do: yum --enablerepo "updates-testing" update kernel Thanks for reporting and patience. |
