Screwed up my .config, and had CONFIG_FW_LOADER_USER_HELPER inadvertantly set
Odd though that it causes that 60 second delay, given that it's supposedly a
'fallback' when the direct loading fails.

It seems I don't actually need to set that option, so I'm not bothered
if there's an actual bug here or not, but the behaviour seems odd.
