There are two patches that may help: https://bugzilla.kernel.org/attachment.cgi?id=38502 http://marc.info/?l=linux-wireless&m=129310430012942&w=2 I will prepare test kernel with them ... Please test both these kernels and share your impression: http://koji.fedoraproject.org/koji/taskinfo?taskID=2697824 http://koji.fedoraproject.org/koji/taskinfo?taskID=2698228 I'm affected by the same problem, installing kernel from http://koji.fedoraproject.org/koji/taskinfo?taskID=2698228 now. This kernel fixes the problem for me (didn't test the other build). [khautio@kha ~]$ uname -a Linux kha 2.6.35.10-75.irq.fc14.i686 #1 SMP Mon Jan 3 14:49:06 UTC 2011 i686 i686 i386 GNU/Linux The irq build didn't fix my issue, I'm trying the low_ack kernel now. Jan 4 16:01:07 emma kernel: [ 0.000000] Linux version 2.6.35.10-75.irq.fc14.x86_64 (mockbuild.fedoraproject.org) (gcc version 4.5.1 20100924 (Red Hat 4.5.1-4) (GCC) ) #1 SMP Mon Jan 3 14:34:56 UTC 2011 [...] Jan 4 17:37:37 emma kernel: [ 5810.255040] iwlagn 0000:04:00.0: iwlagn_tx_agg_start on ra = 00:25:9c:d2:4d:a0 tid = 0 Jan 4 17:37:44 emma kernel: [ 5816.994056] iwlagn 0000:04:00.0: BA scd_flow 0 does not match txq_id 10 Jan 4 17:37:45 emma kernel: [ 5818.095818] iwlagn 0000:04:00.0: BA scd_flow 0 does not match txq_id 10 Jan 4 17:37:46 emma kernel: [ 5819.064689] iwlagn 0000:04:00.0: low ack count detected, restart firmware Jan 4 17:37:46 emma kernel: [ 5819.064701] iwlagn 0000:04:00.0: On demand firmware reload Jan 4 17:37:46 emma kernel: [ 5819.119974] iwlagn 0000:04:00.0: Stopping AGG while state not ON or starting Jan 4 17:37:46 emma kernel: [ 5819.119986] iwlagn 0000:04:00.0: queue number out of range: 0, must be 10 to 19 Jan 4 17:38:01 emma kernel: [ 5834.658906] iwlagn 0000:04:00.0: iwlagn_tx_agg_start on ra = 00:25:9c:d2:4d:a0 tid = 0 Jan 4 17:38:04 emma kernel: [ 5837.085846] iwlagn 0000:04:00.0: low ack count detected, restart firmware Jan 4 17:38:04 emma kernel: [ 5837.085853] iwlagn 0000:04:00.0: On demand firmware reload Jan 4 17:38:04 emma kernel: [ 5837.136528] iwlagn 0000:04:00.0: Stopping AGG while state not ON or starting Jan 4 17:38:04 emma kernel: [ 5837.136535] iwlagn 0000:04:00.0: queue number out of range: 0, must be 10 to 19 Jan 4 17:42:51 emma kernel: imklog 4.6.3, log source = /proc/kmsg started. There is other similar bug 667459 report, that point the hard lock problem is on mac80211 layer. Please test this kernel and report back: http://koji.fedoraproject.org/koji/taskinfo?taskID=2704610 James, any news on comment 6 (also you can try official build with patch http://koji.fedoraproject.org/koji/buildinfo?buildID=213595 if you wish). I haven't tested the comment 6 build yet---it will be another week before I can, unfortunately---but I did see the same problem with the low_ack kernel. Please save packages you need from comment 6 as koji can remove these files automaticly. With low_ack kernel at least :low ack count detected, restart firmware" should gone. Got it, thanks. I'm going to test comment 7 build now Kari and/or James could you test driver from upstream with some my patches: https://bugzilla.redhat.com/show_bug.cgi?id=648732#c21 Posted to fedora and stable. http://lists.fedoraproject.org/pipermail/kernel/2011-May/003091.html kernel-2.6.38.6-27.fc15 has been submitted as an update for Fedora 15. https://admin.fedoraproject.org/updates/kernel-2.6.38.6-27.fc15 Package kernel-2.6.38.6-27.fc15: * should fix your issue, * was pushed to the Fedora 15 testing repository, * should be available at your local mirror within two days.
