Comment 1 Reinette Chatre 2010-06-16 20:31:13 UTC
How sporadic are these errors? Do you think you can easily reproduce? Any hints on how I can reproduce here? Please ensure driver is compiled with debug support (CONFIG_IWLWIFI_DEBUG) and then load driver with "modprobe iwlagn debug=0x443fff" - you may have to redirect it all to syslog if it takes some time to reproduce.

Created attachment 26818 [details] Remove key information during device restart One scenario in which this can occur is when there are a few device restarts. have you been seeing those? Could you please try this patch?
Comment 3 Mario Guenterberg 2010-06-17 06:42:27 UTC
I will try the patch later this day. The device may be restarting sometimes, yes. The problem occurs intensified at the end of a long session on my laptop, 12 -14 hours. My notebook stands still at this time, I've worked at my office table all the time. I noticed that NetworkManager reconnected from time to time with the wireless network.
Comment 4 Mario Guenterberg 2010-06-21 21:29:21 UTC
I've applied the patch and build a new kernel with it. I have a new long working session tomorrow. I will see wether it help.
Comment 5 Mario Guenterberg 2010-06-23 23:47:42 UTC
I had yesterday no problems with the network device, anyway not this issue related. Works fine.
