FS#334 - ath5k: kernel warning every 10 minutes

Device: Ubiquiti Routerstation Pro, 1x Mikrotik R52n, 1x Ubiquiti SR71-A, 1x Ubiquiti XR2
LEDE r2473-b305b8c
While testing 802.11w on ath5k, I noticed that a kernel warning occurs every 10 minutes, or when running "wifi". This happens even when no clients are associated. To make sure it is unrelated to my 802.11w changes, I tested with unmodified LEDE r2473-b305b8c.
Wireless config:
config wifi-device 'radio0'
