Hi, The error shown in the SYSASSERT dump looks strange, I couldn't figure much out of it. Could you provide trace-cmd logs, as explained in our debugging wiki page[1]? Please include all the switches mentioned in the "Tracing" section. [1] https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/debugging #tracing -- Cheers, Luca.
