I recently got the error message I mentioned in the subject of this report, see attached journalctl-dmesg output line 66. Situation was the laptop running for multiple days, suspended multiple times (I heard that sometimes triggers the Queue stuck bug). Above bug happened while capturing traffic with airodump-ng on a fixed g channel, iwlwifi was loaded with 11n_disabled=1, after about one hour. Could not reproduce it but it sounds really serious. Can I do anything to help debug this problem?
