Any chance you can try these same tests with latest code
(compat-wireless may be easiest) to help us determine if this is still
an issue?

We could maybe at least figure out what is going on here if the driver
is loaded with some debugging. Please ensure driver is compiled with
debugging (CONFIG_IWLWIFI_DEBUG) and load the module with "modprobe
iwlagn debug=0x43fff". Could you please reproduce under this
environment?
