compile the kernel with CONFIG_IWLWIFI_DEVICE_TRACING and
CONFIG_IWLWIFI_DEBUG set.
Then, compile trace-cmd
(https://git.kernel.org/cgit/linux/kernel/git/rostedt/trace-cmd.git/)
Finally as root:
trace-cmd record -e iwlwifi -e iwlwifi_dbg
Run the failing scenario - until you get the warning.
you'll get a trace.dat file. Compress it and send it to me.
If you can't make it work - please enable CONFIG_IWLWIFI_DEBUG and
load the iwlwifi module with:
debug=0xC0800000 and send the dmesg output / syslog when the WARNING
occurs. This option is less preferred though.

Excellent, I'll try to get this to you by end of day / evening tomorrow.
