Currently I'm not sure whether it's an issue of iwlwifi or wireless stack. The warning indicates a wrong hw_queue being passed in tx ops. Also it's interesting it's always TX 5... -- You are receiving this mail because: You are the assignee for the bug.

The upstream bug report mentions that it is probably still not fixed.
Enzo, are you able to reproduce it even with TW latest kernel (5.16 as of now)?
Not by closing laptop lid, but I can reproduce with "rfkill block 0" (as mentioned in the upstream report). Same backtrace, also on queue 5. -- You are receiving this mail because: You are the assignee for the bug.

A pity though. I am not sure we have an internal expert on the wireless stack and drivers around. Anyway, since it is the upstream bug, the ball is mainly on that side. -- You are receiving this mail because: You are the assignee for the bug.
