Created attachment 288249 [details] dmesg with latest kernel and latest freezing My system often freezes when connected to a wifi hotspot. Usually around 10-15 minutes of computer usage. And especially when playing videos, music, and also when downloading fairly large files using XDM and torrenting via QBittorrent. After my system is frozen. I can't restore my connection, when I unplug my wifi adapter, suddenly everything freezes. The music I'm playing is playing repeatedly/on loop. Until finally I had to force a reboot by pressing the reset button on my PC.

As when hif_usb_send_regout fails, the urb callback frees the skb, but we free the skb in ath9k_wmi_cmd again.
