Extra dice are not multiplied when scoring a critical hit.
Thanx for your objection. "Extra Dice are not multiplied" [see PHB, p. 140, sidebar] ..., hmm ..., than it makes for a *meager* 28.5 [2d8 + 2d6 +1d12 + 2 + 4] points of damage. At least it's considerable.
"You can't add the bonus from Power Attack to the damage dealt with a light weapon (except with unarmed strikes or natural weapon attacks [...]" PHB, p. 98, Power Attack. OK, thanx for that one.
Aha..., "An unarmed strike is always considered a light weapon." PHB, p. 121, Strike, Unarmed. Thanx for that one, too.
Kind regards
P.S.: A friend of mine used to play a dwarven druid clad in Rhino Hide (3.0, that is!!!) with
Brambles cast on his quarterstaff and
Oak's Might cast on him. I don't recall the numbers exactly, but there were at least 40+ damage points per Power Attack hit. He was a killer (in fact, he was a killer....)

We had to remove the Rhino Hide from the game after the dwarven druid met an untimely death.
