Since installing net-wireless/iwl4965-ucode-228.61.2.24 my wireless from time to time stops working. During use (browsing, downloading) the driver seems to crash. 'modprobe -r iwlagn && modprobe iwlagn' does not bring it back, but a reboot does.

I usually suspend (to ram) the computer. Sometimes it takes a week of uptime until this occurs again. I also had this issue with kernel 2.6.31, but not before. 

It is pretty hard to reproduce. I attached portions of /var/log/messages which are printed when this happens.

Hardware is an Lenovo Thinkpad x61s with intel wireless card 4965

Sorry for fuzzyness. I will try take take whatever debugging actions I can to provide more information.

Reproducible: Sometimes

Note: the bug occured with gentoo-sources-2.6.32! 
emerge --info shows vanilla sources since I installed these to reproduce and submit to kernel bugzilla.

Thank you for report Thomas. Unfortunately kernel log has only addresses and no function names:

Dec 31 11:03:23 denkmatte kernel: [<c01aca00>] ? 0xc01aca00

Probably you logger has no access to System.map, so please, fix this. After that, could you read the following: http://intellinuxwireless.org/?n=fw_error_report , report bug upstream: http://bugzilla.intellinuxwireless.org/ and drop a link here? Also what happens if you downgrade firmware?

Well, I now have set up everything to log this the next time it occurs. But it seems hard to reproduce... 
When I first encountered this, I downgraded to net-wireless/iwl4965-ucode-228.57.2.23 which seemed to solve the problem.

Despite serious attempts I can't reproduce this lately. 
Closing as Test-Request for the time being. Thanks for answering in any case.
