When do I roll versus Unconsciousness for hitting or going below 0 HP?
This is a thorny one, but has a Kromm clarification.
As per Basic pg 419:
"In addition to the above effects, make a HT roll at the start of your next turn, at -1 per full multiple of HP below zero."
This is the rule I've always gone by... however... according to Kromm Basic 380 offers an incongruity:
The Kromm quote:

Kromm:
Per p. B380, "If you have
zero or fewer HP left . . . You must roll vs. HT
each turn to avoid falling unconscious." The current turn isn't excepted. You're supposed to roll on being taken to 0 HP or below. Injury effects are meant to be immediate – you don't wait a beat and
then notice that your arm is off or your brains are scrambled.
The offending passage is on p. B419:
"In addition to the above effects, make a HT roll at the start of your next turn, at -1 per full multiple of HP below zero."
which would be clearer as:
"In addition to the above effects, make an immediate HT roll, at -1 per full multiple of HP below zero."
The later text:
Success means you can act normally, but must roll again every turn to continue functioning.
would then be better as:
Success means you can act normally, but must roll again at the start of every turn to continue functioning.
My argument: This has never been FAQed, Kromm is off his nut on the happy herb.
Counter argument: Kromm is the Line Editor of GURPS.
