On 2.6.29.4, I just got a crash in iwlagn under heavy network
throughput. I was transferring a dvd iso from one box in my
lan to another, and the following occurred:

It didn't bring the entire system to a halt (thankfully);
removing and reloading the iwlagn module made everything
just fine. :-)
If any more information is needed, let me know. I'm more than
willing to test patches and such...

Kernel driver in use: iwlagn
Kernel modules: iwlagn
We released new ucode for 4965, 5100, 5300, and 5350 that address this
issue. The new 4965 ucode should work fine with your driver. If you are
using later hardware then you need a more recent driver to be able to
use its new ucode.
You can download the new ucode from:
http://intellinuxwireless.org/?n=Downloads
Best I can tell, I'll need 2.6.30 for the new 5100 firmware, as 2.6.29.4
doesn't seem to care that the newer firmware is present:
root@liberty:~# ls /lib/firmware/iwlwifi-5000-*
/lib/firmware/iwlwifi-5000-1.ucode /lib/firmware/iwlwifi-5000-2.ucode
... and from dmesg:
iwlagn 0000:03:00.0: firmware: requesting iwlwifi-5000-1.ucode
iwlagn loaded firmware version 5.4.1.16
I guess I'll have to wait a bit, as 2.6.30 is off the table for now.
No big deal - at least it's fixed, even if not for me yet.
Thanks!
