Hi Greg (et all),

Note several people are already working on this, so you may already have a request for this.

The "ath9k: Fix general protection fault in ath9k_hif_usb_rx_cb" commit which has been added to several stable kernels (at least to 5.4.y and 5.7.y, but likely also to others) is breaking networking for people with an ath9k card.

A revert has been submitted upstream, but it does not seem to have found it way upstream yet. It has been cherry-picked by the Arch people:

https://git.archlinux.org/linux.git/commit/?h=v5.7.8-arch1&id=1a32e7b57b...

So if you want to credit some of the original people working on fixing this, you can find the revert submitted upstream there.

Reverting this fixes / also see:

Now reverted, thanks!
