Description Phil Linttell 2009-06-08 04:13:57 UTC
Created attachment 21804 [details] lspci -vvnn I'm running ubuntu karmic alpha 1 and with kernel 2.6.30-7 and 2.6.30-8 wireless networking dies shortly after boot-up with the following message in the log: [ 6163.608689] ath9k: received PCI FATAL interrupt [ 6167.608585] wlan0: no probe response from AP 00:18:39:6f:60:02 - disassociating This does not occur under with kernel 220.127.116.11 or 18.104.22.168 on the same system. I can get networking working again for a short time with: modprobe -r ath9k modprobe ath9k /etc/init.d/networking restart But it will soon die again with the same message. My wireless networking has been solid for months, and only fails under 2.6.30.

Tested as well with my distribution's release of 2.6.30-9. Same error. The log below shows that it recovered twice, briefly, but after that seemed to stay down... at least until I rebooted back with 22.214.171.124.

Comment 2 Jouni Malinen 2009-06-16 13:27:25 UTC
I hit an issue that may be caused by the same issue. This was resolved by reverting an earlier change in ath9k. I've submitted a fix for this and will hopefully be available in wireless-testing.git eventually (and also as a 2.6.30.x stable release). If you have a chance to test the patch by building a modified kernel version yourself, you can find the submission from http://article.gmane.org/gmane.linux.kernel.wireless.general/34741
Comment 3 Phil Linttell 2009-06-16 16:37:08 UTC
Hi Jouni, Thanks! I applied the patch to my distribution's source for 2.6.30-9. I can confirm that the PCI FATAL error message has gone away and my networking is again stable. (Posting this now with it running.) How can I follow the progress of the patch to know when it goes into a stable release? Phil
