Thanks for the bug report.

Could you please try the attached patch, as it fixes the problem for me.
It would be really nice if you could run your test once with SW crypto and
another time with HW crypto.
SW crypto is the default behaviour, so you can just run "modprobe iwl3945"
For HW crypto, you'll have to run "modprobe iwl3945 swcrypto=0"

Thanks in advance.

Yes. After applying this patch to commit
e98df74b724417607e039a4e0b28ad230e5e9b96, this bug is fixed.

I tried both software/hardware crypto with WPA2 PSK and EAP.

Mark as fixed.
