Thanks for the report. It looks like there's some problem with TDLS. I'd like to ask you to collect some debug data, if possible. Firstly, please provide a firmware dump as per the instructions provided in [1]. Additionally, it would be helpful if you could test our latest driver from [2], which contains commits that have not yet been submitted upstream. And the last request - could you please open a bugzilla ticket and share the debug data there, the process is also described in [1]. [1] https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/debugging [2] https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
