Comment (by el_goretto):
Additionnal info to the previous comment (that was mine): it is not
related to scan operations.
After several days on channel 48 (no DFS required), I had no {{{failed to
process fft report: -22}}} log entry and the channel was stable.
I changed the channel yesterday (first line of the following log entries)
to auto (which resulted in channel 116 being selected when {{{wlan0: link
becomes ready}}} shows up) and the issue happened again (wlan0 is the
ath10k interface):

After this last line, the channel was set to 36 but I still could initiate
a scan operation.
