Subjectiwlwifi: Regression after migrating to 6.6.32
Hi,

After upgrading from kernel 5.10.y to 6.6.32 on an i.MX8MM IoT Gateway board,
I started seeing the following storm of iwlwifi warnings (these warnings
keep coming in a loop):

[ 6.995391] ------------[ cut here ]------------

Does anyone have any suggestions on how to fix this for 6.6.y?

Thanks,

Fabio Estevam
