* iwl3945 bug in 2.6.34 @ 2010-05-23 6:25 Satish Eerpini 2010-05-24 18:03 ` John W. Linville 2010-05-24 18:33 ` reinette chatre 0 siblings, 2 replies; 11+ messages in thread From: Satish Eerpini @ 2010-05-23 6:25 UTC (permalink / raw) To: linux-kernel; +Cc: linux-wireless hello, I am running a custom compiled 2.6.34 (fedora 12) on a hp nx7400 with a Intel Pro Wireless 3945 card, the card works fine and connects to a WEP secure wireless connection on my router. But after some time network manager starts reporting that the wireless access point is not available anymore and tries to reconnect to the network, though the network is still available, it fails to detect the network , I have not been able to reproduce the situation conclusively, seems to be happening randomly ... here is the tail from "dmesg" which looked suspicious : (btw, I also faced the same problem earlier when I was running RHEL beta 6.0 on the same machine) No probe response from AP 00:1b:da:2a:a1:53 after 500ms, disconnecting. iwl3945 0000:10:00.0: Error sending REPLY_RXON: time out after 500ms. iwl3945 0000:10:00.0: Error setting new configuration (-110). iwl3945 0000:10:00.0: Error sending REPLY_RXON: time out after 500ms. iwl3945 0000:10:00.0: Error setting new configuration (-110). cfg80211: Calling CRDA to update world regulatory domain cfg80211: Calling CRDA for country: IN cfg80211: Regulatory domain changed to country: IN (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) (2402000 KHz - 2482000 KHz @ 40000 KHz), (N/A, 2000 mBm) (5170000 KHz - 5250000 KHz @ 20000 KHz), (N/A, 2000 mBm) (5250000 KHz - 5330000 KHz @ 20000 KHz), (N/A, 2000 mBm) (5735000 KHz - 5835000 KHz @ 20000 KHz), (N/A, 2000 mBm) iwl3945 0000:10:00.0: Error sending REPLY_RXON: time out after 500ms. iwl3945 0000:10:00.0: Error setting new configuration (-110). iwl3945 0000:10:00.0: Error sending REPLY_SCAN_CMD: time out after 500ms. iwl3945 0000:10:00.0: Error sending REPLY_TX_PWR_TABLE_CMD: time out after 500ms. iwl3945 0000:10:00.0: Error sending REPLY_SCAN_CMD: time out after 500ms. iwl3945 0000:10:00.0: Error sending REPLY_RXON: time out after 500ms. iwl3945 0000:10:00.0: Error setting new configuration (-110). iwl3945 0000:10:00.0: Error sending REPLY_RXON: time out after 500ms. iwl3945 0000:10:00.0: Error setting new configuration (-110). iwl3945 0000:10:00.0: Error sending REPLY_TX_PWR_TABLE_CMD: time out after 500ms. iwl3945 0000:10:00.0: Error sending REPLY_RXON: time out after 500ms. iwl3945 0000:10:00.0: Error setting new configuration (-110). iwl3945 0000:10:00.0: Error sending REPLY_SCAN_CMD: time out after 500ms. iwl3945 0000:10:00.0: Error sending REPLY_TX_PWR_TABLE_CMD: time out after 500ms. iwl3945 0000:10:00.0: Error sending REPLY_SCAN_CMD: time out after 500ms. iwl3945 0000:10:00.0: Error sending REPLY_RXON: time out after 500ms. iwl3945 0000:10:00.0: Error setting new configuration (-110). iwl3945 0000:10:00.0: Error sending REPLY_RXON: time out after 500ms. iwl3945 0000:10:00.0: Error setting new configuration (-110). iwl3945 0000:10:00.0: Error sending REPLY_TX_PWR_TABLE_CMD: time out after 500ms. iwl3945 0000:10:00.0: Error sending REPLY_RXON: time out after 500ms. iwl3945 0000:10:00.0: Error setting new configuration (-110). iwl3945 0000:10:00.0: Error sending REPLY_SCAN_CMD: time out after 500ms. iwl3945 0000:10:00.0: Error sending REPLY_TX_PWR_TABLE_CMD: time out after 500ms. iwl3945 0000:10:00.0: Error sending REPLY_SCAN_CMD: time out after 500ms. iwl3945 0000:10:00.0: Error sending REPLY_RXON: time out after 500ms. iwl3945 0000:10:00.0: Error setting new configuration (-110). iwl3945 0000:10:00.0: Error sending REPLY_RXON: time out after 500ms. iwl3945 0000:10:00.0: Error setting new configuration (-110). iwl3945 0000:10:00.0: Error sending REPLY_TX_PWR_TABLE_CMD: time out after 500ms. iwl3945 0000:10:00.0: No space in command queue iwl3945 0000:10:00.0: Restarting adapter due to queue full iwl3945 0000:10:00.0: Error sending REPLY_RXON: enqueue_hcmd failed: -28 iwl3945 0000:10:00.0: Error setting new configuration (-28). iwl3945 0000:10:00.0: MAC is in deep sleep!.

Or also with Fedora-provided kernels? If the latter, please be sure to open a bug at bugzilla.redhat.com and Cc: linville@redhat.com when you do. > No probe response from AP 00:1b:da:2a:a1:53 after 500ms, disconnecting. > iwl3945 0000:10:00.0: Error sending REPLY_RXON: time out after 500ms. > iwl3945 0000:10:00.0: Error setting new configuration (-110). > iwl3945 0000:10:00.0: Error sending REPLY_RXON: time out after 500ms. > iwl3945 0000:10:00.0: Error setting new configuration (-110). <snip> This looks like the firmware died. Since this is iwl3945, you might try a patch like Reinette suggests here: https://bugzilla.redhat.com/show_bug.cgi?id=589777#c5 Does that enable the device to recover? John -- John W.

This did not use to be an issue with 3945 and unfortunately we do not know what is triggering it now. Please try the "Enable stuck queue detection on 3945" patch that is attached to http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1834 as a workaround.

Actually, sorry, but that patch will not work on 2.6.34 since the feature it enables is not present there - it will be in 2.6.35 though. To enable the feature in 2.6.34 will take some more backporting effort that I'm looking into now. Reinette ^ permalink raw reply [flat|nested] 11+ messages in thread

If that works I will report back (though you might already know if it will work or not) Cheers Satish -- http://tuxitter.blogspot.com -- http://tuxitter.blogspot.com ^ permalink raw reply [flat|nested] 11+ messages in thread

When a queue is stuck for some unknown conditions causing the throughput to drop and the transfer is stop, the driver will force firmware reload and bring the system back to normal operational state. The iwlwifi devices behave differently in this regard so this feature is made part of the ops infrastructure so we can have more control on how to monitor and recover from tx queue stall case per device.

I've tried to increase timeout to 100 but the result is the same. I can't apply this patches because base is somewhat different, as I can see the first patch is already applied but the second one isn't. Any suggestions ? Thanks. In the meantime I will try to get some more debug information. ^ permalink raw reply [flat|nested] 11+ messages in thread
