Started rising also inside base in revolt (6,2)

Ross

I believe the answer is:

booted up

'started' is the definition.
(as in booting up a computer)

'rising also inside base in revolt' is the wordplay.
'rising also inside base' becomes 'booted' (I can't justify this - if you can you should give a lot more credence to this answer).
'in revolt' becomes 'up' (I've seen this in other clues).
'booted'+'up'='BOOTED UP'

I've seen this clue in The Guardian.
