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 26.6.29.2. [ 234.737624] ath9k: received PCI FATAL interrupt [ 238.736525] wlan0: no probe response from AP 00:18:39:6f:60:02 - disassociating [ 239.608827] wlan0: authenticate with AP 00:18:39:6f:60:02 [ 239.611346] wlan0: authenticated [ 239.611356] wlan0: associate with AP 00:18:39:6f:60:02 [ 239.615507] wlan0: RX ReassocResp from 00:18:39:6f:60:02 (capab=0x411 status=0 aid=1) [ 239.615516] wlan0: associated [ 369.481780] ath9k: received PCI FATAL interrupt [ 373.480552] wlan0: no probe response from AP 00:18:39:6f:60:02 - disassociating [ 374.325108] wlan0: authenticate with AP 00:18:39:6f:60:02 [ 374.329847] wlan0: authenticate with AP 00:18:39:6f:60:02 [ 374.332351] wlan0: authenticated [ 374.332357] wlan0: associate with AP 00:18:39:6f:60:02 [ 374.339310] wlan0: RX ReassocResp from 00:18:39:6f:60:02 (capab=0x411 status=0 aid=1) [ 374.339315] wlan0: associated [ 486.940779] ath9k: received PCI FATAL interrupt [ 490.936530] wlan0: no probe response from AP 00:18:39:6f:60:02 - disassociating 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 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 Can someone please close this bug now? |
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 2.6.29.2 or 2.6.29.1 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.
