Is this new?  I use wpa_cli regularly but after a full VM update to main Nov 3
I do see it too now.  I definitively used scan and scan_results a lot a while
ago (around 3f382eb23b9f).

Selected interface 'wlan0'

Interactive mode

> scan_results
'SCAN_RESULTS' command timed out.

I've not seen this error before.  Time to ktrace?
